By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + <one line to give the program's name and a brief idea of what it does.> + Copyright (C) <year> <name of author> + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA + + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + <signature of Ty Coon>, 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs. If your program is a subroutine library, you may +consider it more useful to permit linking proprietary applications with the +library. If this is what you want to do, use the GNU Library General +Public License instead of this License. diff --git a/ChangeLog b/ChangeLog new file mode 100644 index 0000000..2991320 --- /dev/null +++ b/ChangeLog @@ -0,0 +1,431 @@ +2005-09-20 Jose Antonio Ortega Ruiz <jao@gnu.org> + + * mdk: version 1.2.1 tagged (v1r2_1). + + * doc/mdk_copying.texi: FDL license updated to 1.2. + + * mdk (Module): FSF address updated. + + * mixguile/xmixguile_cmd_dispatcher.c (Module): use unsigned int + for length parameters. + + * doc/mdk_tut.texi: compliance with 'traditional' ALF directive + documented. + +2005-09-19 Jose Antonio Ortega Ruiz <jao@gnu.org> + + * po/de.po: corrections by Jens Seidel. + + * mixgtk/Makefile.am (AM_LDFLAGS): fix libglade dynamic linking. + + * mixutils/mixasm.c:improve -g handling (accept it to not break + potential user scripts) + +2005-04-05 Pieter Pareit <pieter.pareit@scarlet.be> + + * mixutils/mixasm.c: make handeling of arguments somewhat robuster. + + * misc/mixal-mode.el: -g option no longer needed on compilation. + + * doc/mdk_mixasm.texi: fix of grammer mistake. + +2005-03-26 Sergey Poznyakoff <gray@gnu.org> + + * mixlib/mix_scanner.l (ENTER_WEVAL) Accept an argument, specifying + how many characters to exclude from yyless. + (ws): Removed '+' closure.

tarball +=========================== + + GNU MDK is distributed as a source tarball available for download in +the following URLs: + + * <ftp://ftp.gnu.org/pub/gnu/mdk> (or one of its mirrors + (http://www.gnu.org/prep/ftp.html)) + + * `http://sourceforge.net/project/showfiles.php?group_id=13897' + + The above sites contain the latest stable releases of MDK. The +development branch is available at: + + * `https://savannah.gnu.org/cvs/?group_id=118' + + After you have downloaded the source tarball, unpack it in a +directory of your choice using the command: + + tar xfvz mdk-X.Y.tar.gz + +where X.Y stands for the downloaded version (the current stable release +being version 1.2.1). + +Requirements +============ + + In order to build and install MDK, you will need the following +libraries installed in your system: + + - GLIB 2.4.0 (http://www.gtk.org) (required) + + - GNU Flex 2.5 (http://www.gnu.org/software/flex/flex.html) + (required) + + - GTK 2.4.0 (http://www.gtk.org) (optional) + + - Libglade 2.4.0 (http://ftp.gnome.org/pub/GNOME/sources/libglade/2.4/) + (optional) + + - GNU Readline + (http://cnswww.cns.cwru.edu/php/chet/readline/rltop.html) + (optional) + + - GNU Libguile 1.6 (http://www.gnu.org/software/guile) (optional) + + If present, readline and history are used to provide command +completion and history management to the command line MIX virtual +machine, `mixvm'. GTK+ and libglade are needed if you want to build +the graphical interface to the MIX virtual machine, `gmixvm'. Finally, +if libguile is found, the MDK utilities will be compiled with Guile +support and will be extensible using Scheme. + + *Please note*: you need both the libraries _and_ the headers; this +means both the library package and the `-dev' package if you do not +compile your libraries yourself (ex: installing `libgtk2.0' and +`libgtk2.0-dev' on Debian). + +Basic installation +================== + + MDK uses GNU Autoconf and Automake tools, and, therefore, should be +built and installed without hassle using the following commands inside +the source directory: + + ./configure + make + make install + +where the last one must be run as root. + + The first command, `configure', will setup the makefiles for your +system. In particular, `configure' will look for GTK+ and libglade, +and, if they are present, will generate the appropiate makefiles for +building the `gmixvm' graphical user interface. Upon completion, you +should see a message with the configuration results like the following: + + *** GNU MDK 1.2.1 has been successfully configured. *** + + Type 'make' to build the following utilities: + - mixasm (MIX assembler) + - mixvm (MIX virtual machine, with readline support, + with guile support) + - gmixvm (mixvm GTK+ GUI, with guile support) + - mixguile (the mixvm guile shell) + +where the last lines may be missing if you lack the above mentioned +libraries. + + The next command, `make', will actually build the MDK programs in +the following locations: + + - `mixutils/mixasm' + + - `mixutils/mixvm' + + - `mixgtk/gmixvm' + + - `mixguile/mixguile' + + You can run these programs from within their directories, but I +recommend you to install them in proper locations using `make install' +from a root shell. + +Emacs support +============= + + `mixvm' can be run within an Emacs GUD buffer using the elisp +program `misc/mixvm.el', kindly contributed by {No value for `PHILIP'}. + + `mixvm.el' provides an interface between MDK's `mixvm' and Emacs, +via GUD. Place this file in your load-path, optionally adding the +following line to your `.emacs' file: + + (autoload 'mixvm "mixvm" "mixvm/gud interaction" t) + +Special configure flags +======================= + + You can fine tunning the configuration process using the following +switches with configure: + + - User Option: -enable-gui[=yes|no] + - User Option: -disable-gui + Enables/disables the build of the MIX virtual machine GUI + (`gmixvm'). If the required libraries are missing (*note + Requirements::) the configure script with automatically disable + this feature. + + - User Option: -with-guile[=yes|no] + - User Option: -without-guile + Enables/disables the Guile support for `mixvm' and `gmixvm', and + the build of `mixguile'.

This source code distribution is autoconfiguring and you should be +able to compile it and install it without manual interventions such as +editing Makefiles, configuration files, and so on. These are generic +instructions for people who are not familiar with installing autoconfiguring +software. + +The simplest way to compile this package is to enter the source code +main directory and do the following: + + 1. Configure the source code by typing: + % sh ./configure + + If you're planning to install the package into your home directory + or to a location other than `/usr/local' then add the flag + `--prefix=PATH' to `configure'. For example, if your home directory + is `/home/luser' you can configure the package to install itself there + by invoking: + % sh ./configure --prefix=/home/luser + + While running, `configure' prints some messages telling which + features is it checking for. + + 2. Compile the package by typing: + % make + Running `make' takes a while. If this is a very large package, now + is the time to go make some coffee. + + 3. Some packages are bundled with self-tests for source-code + verification. If this package includes such tests, you can + optionally run them after compilation by typing + % make check + + 4. Type `make install' to install the programs and any data files and + documentation. Type `make uninstall' to undo the installation. + During installation, the following files go to the following directories: + Executables -> /prefix/bin + Libraries -> /prefix/lib + Public header files -> /prefix/include + Man pages -> /prefix/man/man? + Info files -> /prefix/info + where `prefix' is either `/usr/local' or the PATH that you specified + in the `--prefix' flag. + + If any of these directories do not presently exist, they will be + created on demand. + + If you are installing in your home directory make sure that + `/home/luser/bin' is in your path. If you're using the bash shell + add this line at the end of your .cshrc file: + PATH="/home/luser/bin:${PATH}" + export PATH + If you are using csh or tcsh, then use this line instead: + setenv PATH /home/luser/bin:${PATH} + By prepending your home directory to the rest of the PATH you can + override systemwide installed software with your own custom installation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. + +Compiler configuration +====================== + + The `configure' shell script is responsible for choosing and configuring +the compiler(s). + +The following options allow you to specify whether you +want to enable or disable various debugging mechanisms: + +`--with-warnings' + Make the compilers very picky about warnings. Try this whenever you + write new code since it may catch a few bugs. This is not active by + default because all too often warnings can be too picky and scare + the end-user. + +`--disable-assert' + Compile without using assertions. This results in faster code, + but should not be used during developerment, or to run `make check' + which depends on assertions. It should only be used for production + runs on code that you believe is bug free. + +All programs are compiled with optimization level 2 by default (-O2). +Occasionally that confuses the debugger when code is inlined. To disable +optimization and enable debugging, set the shell environment variables +CFLAGS, CXXFLAGS, FFLAGS to `-g'. On the bash shell, you can do this +like this: + $ export CFLAGS="-g" + $ export CXXFLAGS="-g" + $ export FFLAGS="-g" +On the tcsh shell, use the `setenv' command instead: + % setenv CFLAGS "-g" + ...etc... +For other shell, please consult your shell's documentation. + +Similarly, you can increase the optimization level by assigning these +variables to "-g -O3". + +The following options allow you to reconsider the `configure' shell script's +choice of Fortran compilers. + +`--with-f2c' + Compile the Fortran code by translating it to C, even if a native + Fortran compiler is available. A copy of the f2c translator should be + bundled in the distribution. It will be compiled and then used to + compile your Fortran code. +`--with-g77' + Compile the Fortran code with g77 even if a proprietary Fortran + compiler is available +`--with-f77=F77' + Compile the Fortran code with the specified Fortran compiler. + +Depending on what languages the package uses, some of these options may +or may not be available. To see what is available, type: + % sh ./configure --help + +About the configure script +========================== + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, a file +`config.cache' that saves the results of its tests to speed up +reconfiguring, and a file `config.log' containing compiler output +(useful mainly for debugging `configure'). + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If at some point `config.cache' +contains results you don't want to keep, you may remove or edit it. + + The file `configure.in' is used to create `configure' by a program +called `autoconf'. You only need `configure.in' if you want to change +it or regenerate `configure' using a newer version of `autoconf'. + +Advanced installation options. +============================== + + The `configure' script also understands the following more advanced +options, to handle situations for which `--prefix' alone is not sufficient. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +give `configure' the option `--exec-prefix=PATH', the package will use +PATH as the prefix for installing programs and libraries. +Documentation and other data files will still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=PATH' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +---- + +$Id: INSTALL,v 1.7 2005/09/20 20:18:58 jao Exp $ diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 0000000..cfd46d1 --- /dev/null +++ b/Makefile.am @@ -0,0 +1,24 @@ +## Process this file with automake to produce Makefile.in + +# Copyright (C) 2000, 2001, 2004 Free Software Foundation, Inc. +# +# This file is free software; as a special exception the author gives +# unlimited permission to copy and/or distribute it, with or without +# modifications, as long as this notice is preserved. +# +# This program is distributed in the hope that it will be useful, but +# WITHOUT ANY WARRANTY, to the extent permitted by law; without even the +# implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. + +EXTRA_DIST = config.rpath ABOUT-NLS intltool-extract.in intltool-merge.in \ + intltool-update.in +SUBDIRS = po intl doc lib mixlib mixguile mixutils mixgtk misc samples + +distclean-local: + rm -f intltool-extract + rm -f intltool-merge + rm -f intltool-update + +docdir = $(top_builddir)/doc + +ACLOCAL_AMFLAGS = -I m4 @@ -0,0 +1,450 @@ +GNU MDK -- History of visible changes. + +Copyright (C) 2000, 2001, 2002, 2003, 2004, 2005, Free Software Foundation, Inc. +See the end for copying conditions. + +Please send mdk bug reports to bug-mdk@gnu.org. + +--------------------------------------------------------------------------- +* Version 1.2.1 (20/09/05) + +** MIXAL compliance improvements (Sergey Poznyakoff): + + - w-expressions in literals are now admitted (e.g. LDA =8(1:1)=) + - ALF now accepts non-quoted arguments (in addition to quoted + - ones), as in the original TAOCP definition. + +** German translation updated (thanks to Jens Seidel) + +** mixal.el improvements (Pieter Pareit) + +** Bug fixes: + + - gmixvm's failure to dynamically link with libglade (#13661) + (thanks to Sascha Wilde) + - mixal.el calls mixasm with obsolete -g option (#14569) (thanks to + Sascha Wilde) + - mixasm -g causes a coredump (#14579) (Pieter Pareit) + +--------------------------------------------------------------------------- +* Version 1.2 (05/08/04) + +** Graphical user interface (gmixvm) updated to gtk+ 2.4.x + + - gmixvm now uses the latest version of the gtk+ toolkit, including + antialiased Pango fonts. + - Individually detachable windows for the virtual machine, the + source window and the devices notebook (there is no 'split mode' + anymore). + - Detachable toolbars. + - Current source line and breakpoints are now marked via icons. + - New menu option to change all fonts at once. + +** German i18n available (thanks to Mike Scholz).

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software---to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + +@iftex +@unnumberedsec TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION +@end iftex +@ifinfo +@center TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION +@end ifinfo + +@enumerate +@item +This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The ``Program'', below, +refers to any such program or work, and a ``work based on the Program'' +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term ``modification''.) Each licensee is addressed as ``you''. + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + +@item +You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + +@item +You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + +@enumerate a +@item +You must cause the modified files to carry prominent notices +stating that you changed the files and the date of any change. + +@item +You must cause any work that you distribute or publish, that in +whole or in part contains or is derived from the Program or any +part thereof, to be licensed as a whole at no charge to all third +parties under the terms of this License. + +@item +If the modified program normally reads commands interactively +when run, you must cause it, when started running for such +interactive use in the most ordinary way, to print or display an +announcement including an appropriate copyright notice and a +notice that there is no warranty (or else, saying that you provide +a warranty) and that users may redistribute the program under +these conditions, and telling the user how to view a copy of this +License. (Exception: if the Program itself is interactive but +does not normally print such an announcement, your work based on +the Program is not required to print an announcement.) +@end enumerate + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + +@item +You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + +@enumerate a +@item +Accompany it with the complete corresponding machine-readable +source code, which must be distributed under the terms of Sections +1 and 2 above on a medium customarily used for software interchange; or, + +@item +Accompany it with a written offer, valid for at least three +years, to give any third party, for a charge no more than your +cost of physically performing source distribution, a complete +machine-readable copy of the corresponding source code, to be +distributed under the terms of Sections 1 and 2 above on a medium +customarily used for software interchange; or, + +@item +Accompany it with the information you received as to the offer +to distribute corresponding source code. (This alternative is +allowed only for noncommercial distribution and only if you +received the program in object code or executable form with such +an offer, in accord with Subsection b above.) +@end enumerate + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + +@item +You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + +@item +You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + +@item +Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + +@item +If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + +@item +If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + +@item +The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and ``any +later version'', you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + +@item +If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + +@iftex +@heading NO WARRANTY +@end iftex +@ifinfo +@center NO WARRANTY +@end ifinfo + +@item +BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.

It +complements the GNU General Public License, which is a copyleft +license designed for free software. + +We have designed this License in order to use it for manuals for free +software, because free software needs free documentation: a free +program should come with manuals providing the same freedoms that the +software does. But this License is not limited to software manuals; +it can be used for any textual work, regardless of subject matter or +whether it is published as a printed book. We recommend this License +principally for works whose purpose is instruction or reference. + +@item +APPLICABILITY AND DEFINITIONS + +This License applies to any manual or other work, in any medium, that +contains a notice placed by the copyright holder saying it can be +distributed under the terms of this License. Such a notice grants a +world-wide, royalty-free license, unlimited in duration, to use that +work under the conditions stated herein. The ``Document'', below, +refers to any such manual or work. Any member of the public is a +licensee, and is addressed as ``you''. You accept the license if you +copy, modify or distribute the work in a way requiring permission +under copyright law. + +A ``Modified Version'' of the Document means any work containing the +Document or a portion of it, either copied verbatim, or with +modifications and/or translated into another language. + +A ``Secondary Section'' is a named appendix or a front-matter section +of the Document that deals exclusively with the relationship of the +publishers or authors of the Document to the Document's overall +subject (or to related matters) and contains nothing that could fall +directly within that overall subject. (Thus, if the Document is in +part a textbook of mathematics, a Secondary Section may not explain +any mathematics.) The relationship could be a matter of historical +connection with the subject or with related matters, or of legal, +commercial, philosophical, ethical or political position regarding +them. + +The ``Invariant Sections'' are certain Secondary Sections whose titles +are designated, as being those of Invariant Sections, in the notice +that says that the Document is released under this License. If a +section does not fit the above definition of Secondary then it is not +allowed to be designated as Invariant. The Document may contain zero +Invariant Sections. If the Document does not identify any Invariant +Sections then there are none. + +The ``Cover Texts'' are certain short passages of text that are listed, +as Front-Cover Texts or Back-Cover Texts, in the notice that says that +the Document is released under this License. A Front-Cover Text may +be at most 5 words, and a Back-Cover Text may be at most 25 words. + +A ``Transparent'' copy of the Document means a machine-readable copy, +represented in a format whose specification is available to the +general public, that is suitable for revising the document +straightforwardly with generic text editors or (for images composed of +pixels) generic paint programs or (for drawings) some widely available +drawing editor, and that is suitable for input to text formatters or +for automatic translation to a variety of formats suitable for input +to text formatters. A copy made in an otherwise Transparent file +format whose markup, or absence of markup, has been arranged to thwart +or discourage subsequent modification by readers is not Transparent. +An image format is not Transparent if used for any substantial amount +of text. A copy that is not ``Transparent'' is called ``Opaque''. + +Examples of suitable formats for Transparent copies include plain +@sc{ascii} without markup, Texinfo input format, La@TeX{} input +format, @acronym{SGML} or @acronym{XML} using a publicly available +@acronym{DTD}, and standard-conforming simple @acronym{HTML}, +PostScript or @acronym{PDF} designed for human modification. Examples +of transparent image formats include @acronym{PNG}, @acronym{XCF} and +@acronym{JPG}. Opaque formats include proprietary formats that can be +read and edited only by proprietary word processors, @acronym{SGML} or +@acronym{XML} for which the @acronym{DTD} and/or processing tools are +not generally available, and the machine-generated @acronym{HTML}, +PostScript or @acronym{PDF} produced by some word processors for +output purposes only. + +The ``Title Page'' means, for a printed book, the title page itself, +plus such following pages as are needed to hold, legibly, the material +this License requires to appear in the title page. For works in +formats which do not have any title page as such, ``Title Page'' means +the text near the most prominent appearance of the work's title, +preceding the beginning of the body of the text. + +A section ``Entitled XYZ'' means a named subunit of the Document whose +title either is precisely XYZ or contains XYZ in parentheses following +text that translates XYZ in another language. (Here XYZ stands for a +specific section name mentioned below, such as ``Acknowledgements'', +``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title'' +of such a section when you modify the Document means that it remains a +section ``Entitled XYZ'' according to this definition. + +The Document may include Warranty Disclaimers next to the notice which +states that this License applies to the Document. These Warranty +Disclaimers are considered to be included by reference in this +License, but only as regards disclaiming warranties: any other +implication that these Warranty Disclaimers may have is void and has +no effect on the meaning of this License. + +@item +VERBATIM COPYING + +You may copy and distribute the Document in any medium, either +commercially or noncommercially, provided that this License, the +copyright notices, and the license notice saying this License applies +to the Document are reproduced in all copies, and that you add no other +conditions whatsoever to those of this License. You may not use +technical measures to obstruct or control the reading or further +copying of the copies you make or distribute. However, you may accept +compensation in exchange for copies. If you distribute a large enough +number of copies you must also follow the conditions in section 3. + +You may also lend copies, under the same conditions stated above, and +you may publicly display copies. + +@item +COPYING IN QUANTITY + +If you publish printed copies (or copies in media that commonly have +printed covers) of the Document, numbering more than 100, and the +Document's license notice requires Cover Texts, you must enclose the +copies in covers that carry, clearly and legibly, all these Cover +Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on +the back cover. Both covers must also clearly and legibly identify +you as the publisher of these copies. The front cover must present +the full title with all words of the title equally prominent and +visible. You may add other material on the covers in addition. +Copying with changes limited to the covers, as long as they preserve +the title of the Document and satisfy these conditions, can be treated +as verbatim copying in other respects. + +If the required texts for either cover are too voluminous to fit +legibly, you should put the first ones listed (as many as fit +reasonably) on the actual cover, and continue the rest onto adjacent +pages. + +If you publish or distribute Opaque copies of the Document numbering +more than 100, you must either include a machine-readable Transparent +copy along with each Opaque copy, or state in or with each Opaque copy +a computer-network location from which the general network-using +public has access to download using public-standard network protocols +a complete Transparent copy of the Document, free of added material. +If you use the latter option, you must take reasonably prudent steps, +when you begin distribution of Opaque copies in quantity, to ensure +that this Transparent copy will remain thus accessible at the stated +location until at least one year after the last time you distribute an +Opaque copy (directly or through your agents or retailers) of that +edition to the public. + +It is requested, but not required, that you contact the authors of the +Document well before redistributing any large number of copies, to give +them a chance to provide you with an updated version of the Document. + +@item +MODIFICATIONS + +You may copy and distribute a Modified Version of the Document under +the conditions of sections 2 and 3 above, provided that you release +the Modified Version under precisely this License, with the Modified +Version filling the role of the Document, thus licensing distribution +and modification of the Modified Version to whoever possesses a copy +of it. In addition, you must do these things in the Modified Version: + +@enumerate A +@item +Use in the Title Page (and on the covers, if any) a title distinct +from that of the Document, and from those of previous versions +(which should, if there were any, be listed in the History section +of the Document). You may use the same title as a previous version +if the original publisher of that version gives permission. + +@item +List on the Title Page, as authors, one or more persons or entities +responsible for authorship of the modifications in the Modified +Version, together with at least five of the principal authors of the +Document (all of its principal authors, if it has fewer than five), +unless they release you from this requirement. + +@item +State on the Title page the name of the publisher of the +Modified Version, as the publisher. + +@item +Preserve all the copyright notices of the Document. + +@item +Add an appropriate copyright notice for your modifications +adjacent to the other copyright notices. + +@item +Include, immediately after the copyright notices, a license notice +giving the public permission to use the Modified Version under the +terms of this License, in the form shown in the Addendum below. + +@item +Preserve in that license notice the full lists of Invariant Sections +and required Cover Texts given in the Document's license notice. + +@item +Include an unaltered copy of this License. + +@item +Preserve the section Entitled ``History'', Preserve its Title, and add +to it an item stating at least the title, year, new authors, and +publisher of the Modified Version as given on the Title Page. If +there is no section Entitled ``History'' in the Document, create one +stating the title, year, authors, and publisher of the Document as +given on its Title Page, then add an item describing the Modified +Version as stated in the previous sentence. + +@item +Preserve the network location, if any, given in the Document for +public access to a Transparent copy of the Document, and likewise +the network locations given in the Document for previous versions +it was based on. These may be placed in the ``History'' section. +You may omit a network location for a work that was published at +least four years before the Document itself, or if the original +publisher of the version it refers to gives permission. + +@item +For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve +the Title of the section, and preserve in the section all the +substance and tone of each of the contributor acknowledgements and/or +dedications given therein. + +@item +Preserve all the Invariant Sections of the Document, +unaltered in their text and in their titles.

Emacs already helps you with editing +files, but Emacs can do much more. In particular, looking up +documentation is one of its strong points.

Keep in mind that these are not assembly (MIXAL) +pseudoinstructions.

This can be done with the MIX virtual machine. First you will +need to compile your code into MIX byte code. This can be done within +Emacs with the command @kbd{M-x compile} (@kbd{C-c c}). In case of +compilation errors, you can jump to the offending source code line +with @kbd{M-x next-error}. + +Once the program compiles without errors, you can debug or run +it.

As you can see in the above +sample, each line in a MIXAL file can be divided into four fields +separated by an arbitrary amount of whitespace characters (blanks and or +tabs). While in Knuth's definition of MIXAL each field must start at a +fixed pre-defined column number, the @sc{mdk} assembler loosens this +requirement and lets you format the file as you see fit. The only +restrictions retained are for comment lines (like 1-4) which must begin +with an asterisk (*) placed at column 1, and for the label field (see +below) which, if present, must also start at column 1. The four fields +in each non-comment line are: + +@itemize @minus +@item +an optional label, which either refers to the current memory address (as +@code{START} and @code{MSG} in lines 7 and 9) or a defined symbol +(@code{TERM}) (if present, the label must always start at the first +column in its line, for the first whitespace in the line maks the +beginning of the second field), +@item +an operation mnemonic, which can represent either a MIX instruction +(@code{OUT} and @code{HLT} in lines 7 and 8 above), or an assembly +pseudoinstruction (e.g., the @code{ORIG} pseudoinstruction in line +6@footnote{If an @code{ORIG} directive is not used, the program will +be loaded by the virtual machine at address 0. @code{ORIG} allows +allocating the executable code where you see fit.}. +@item +an optional operand for the (pseudo)instruction, and +@item +an optional free text comment. +@end itemize + +@noindent Lines 9-12 of the @file{hello.mixal} file above also show the +second (and last) difference between Knuth's MIXAL definition and ours: +the operand of the @code{ALF} pseudoinstruction (a word of five +characters) must be quoted using ""@footnote{In Knuth's definition, +the operand always starts at a fixed column number, and the use of +quotation is therefore unnecessary. As @code{mixasm} releases this +requirement, marking the beginning and end of the @code{ALF} operand +disambiguates the parser's recognition of this operand when it includes +blanks. Note that double-quotes (") are not part of the MIX character +set, and, therefore, no escape characters are needed within +@code{ALF}'s operands.}. + +The workings of this sample program should be straightforward if you are +familiar with MIXAL.

They are + +@itemize @bullet +@item +@code{mixvm}, a command line oriented simulator, +@item +@code{gmixvm}, a GTK based graphical interface to @code{mixvm}, and +@item +@code{mixguile}, a Guile shell with a built-in MIX simulator. +@end itemize + +All three simulators accept the same set of user commands, but offer a +different user interface, as noted above. In this section we shall +describe some of these commands, and show you how to use them from +@code{mixvm}'s command line. You can use them as well at @code{gmixvm}'s +command prompt (@pxref{gmixvm}), or using the built-in Scheme primitives +of @code{mixguile} (@pxref{Using mixguile}). + +Using the MIX simulators, you can run your MIXAL programs, after +compiling them with @code{mixasm} into binary @file{.mix} +files. @code{mixvm} can be used either in @dfn{interactive} or +@dfn{non-interactive} mode. In the second case, @code{mixvm} will load +your program into memory, execute it (producing any output due to +MIXAL @code{OUT} instructions present in the program), and exit when +it encounters a @code{HLT} instruction. In interactive mode, you will +enter a shell prompt which allows you issuing commands to the running +virtual machine. This commands will permit you to load, run and debug +programs, as well as to inspect the MIX computer state (register +contents, memory cells contents and so on). + +@menu +* Non-interactive mode:: Running your programs non-interactively. +* Interactive mode:: Running programs interactively. +* Debugging:: Commands for debugging your programs. +@end menu + +@node Non-interactive mode, Interactive mode, Running the program, Running the program +@comment node-name, next, previous, up +@subsection Non-interactive mode +@cindex non-interactive mode + +To make @code{mixvm} work in non-interactive mode, use the @code{-r} +flag. Thus, to run our @file{hello.mix} program, simply type + +@example +mixvm -r hello @key{RET} +@end example + +@noindent at your command prompt, and you will get the following output: + +@example +MIXAL HELLO WORLD +@end example + +@noindent Since our hello world program uses MIX's device number 19 as +its output device (@pxref{Writing a source file}), the output is +redirected to the shell's standard output. Had you used any other MIX +output devices (disks, drums, line printer, etc.), @code{mixvm} would +have created a file named after the device used (e.g. @file{disk4.dev}) +and written its output there@footnote{The device files are stored, by +default, in a directory called @file{.mdk}, which is created in your +home directory the first time @code{mixvm} is run. You can change this +default directory using the command @code{devdir} when running +@code{mixvm} in interactive mode (@pxref{Configuration commands})}. + +The virtual machine can also report the execution time of the program, +according to the (virtual) time spent in each of the binary instructions +(@pxref{Execution times}). Printing of execution time statistics is +activated with the @code{-t} flag; running + +@example +mixvm -t -r hello @key{RET} +@end example + +@noindent +produces the following output: + +@example +MIXAL HELLO WORLD +** Execution time: 11 +@end example + +Sometimes, you will prefer to store the results of your program in MIX +registers rather than writing them to a device. In such cases, +@code{mixvm}'s @code{-d} flag is your friend: it makes @code{mixvm} to +dump the contents of its registers and flags after executing the loaded +program. For instance, typing the following command at your shell's +prompt + +@example +mixvm -d -r hello +@end example + +@noindent you will obtain the following output: + +@example +MIXAL HELLO WORLD +rA: + 00 00 00 00 00 (0000000000) +rX: + 00 00 00 00 00 (0000000000) +rJ: + 00 00 (0000) +rI1: + 00 00 (0000) rI2: + 00 00 (0000) +rI3: + 00 00 (0000) rI4: + 00 00 (0000) +rI5: + 00 00 (0000) rI6: + 00 00 (0000) +Overflow: F +Cmp: E +@end example + +@noindent which, in addition to the program's outputs and execution +time, gives you the contents of the MIX registers and the values of the +overflow toggle and comparison flag (admittedly, rather uninteresting in +our sample). + +As you can see, running programs non-interactively has many +limitations. You cannot peek the virtual machine's memory contents, not +to mention stepping through your program's instructions or setting +breakpoints@footnote{The @code{mixguile} program allows you to execute +arbitrary combinations of @code{mixvm} commands (using Scheme) +non-interactively. @xref{Scheme scripts}.}.

This command enters the +@code{mixvm} command shell. You will be presented the following command +prompt: + +@example +MIX > +@end example + +@noindent The virtual machine is initialised and ready to accept your +commands. The @code{mixvm} command shell uses GNU's readline, so that +you have at your disposal command completion (using @key{TAB}) and +history functionality, as well as other line editing shortcuts common to +all utilities using this library (for a complete description of +readline's line editing usage, see @ref{Command Line +Editing,,,Readline}.) + +@cindex @code{load} +Usually, the first thing you will want to do is loading a compiled MIX +program into memory. This is acomplished by the @code{load} command, +which takes as an argument the name of the @file{.mix} file to be +loaded. Thus, typing + +@example +MIX > load hello @key{RET} +Program loaded. Start address: 3000 +MIX > +@end example + +@noindent will load @file{hello.mix} into the virtual machine's memory +and set the program counter to the address of the first instruction.

You obtain the +elapsed execution time (i.e., the time spent executing instructions +since the last breakpoint), the total execution time for the program up +to now (which in our case coincides with the elapsed time, since there +were no breakpoints), and the total uptime for the virtual machine (you +can load and run more than one program in the same +session)@footnote{Printing of timing statistics can be disabled using +the command @code{timing} (@pxref{Configuration commands}).}. After +running the program, the program counter will point to the address after +the one containing the @code{HLT} instruction. In our case, asking the +value of the program counter after executing the program will give us + +@example +MIX > pc +Current address: 3002 +MIX > +@end example + +@cindex @code{pmem} +@noindent You can check the contents of a memory cell giving its address +as an argument of the command @code{pmem}, like this + +@example +MIX > pmem 3001 +3001: + 00 00 00 02 05 (0000000133) +MIX > +@end example + +@noindent +and convince yourself that address 3001 contains the binary +representation of the instruction @code{HLT}. An address range of the +form FROM-TO can also be used as the argument of @code{pmem}: + +@example +MIX > pmem 3000-3006 +3000: + 46 58 00 19 37 (0786957541) +3001: + 00 00 00 02 05 (0000000133) +3002: + 14 09 27 01 13 (0237350989) +3003: + 00 08 05 13 13 (0002118477) +3004: + 16 00 26 16 19 (0268542995) +3005: + 13 04 00 00 00 (0219152384) +3006: + 00 00 00 00 00 (0000000000) +MIX > +@end example + +@cindex @code{preg} +@noindent +In a similar manner, you can look at the contents of the MIX registers +and flags.

Use @code{next} to step through +the program, running its instructions one by one. To run our +two-instruction @file{hello.mix} sample you can do the following: + +@example +MIX > load hello +Program loaded. Start address: 3000 +MIX > pc +Current address: 3000 +MIX > next +MIXAL HELLO WORLD +Elapsed time: 1 /Total program time: 1 (Total uptime: 1) +MIX > pc +Current address: 3001 +MIX > next +End of program reached at address 3002 +Elapsed time: 10 /Total program time: 11 (Total uptime: 11) +MIX > pc +Current address: 3002 +MIX > next +MIXAL HELLO WORLD +Elapsed time: 1 /Total program time: 1 (Total uptime: 12) +MIX > +MIX > run +Running ... +... done +Elapsed time: 10 /Total program time: 11 (Total uptime: 22) +MIX > +@end example +@noindent +(As an aside, the above sample also shows how the virtual machine +handles cummulative time statistics and automatic program restart). + +@cindex @code{sbpa} +@cindex breakpoints + +You can set a breakpoint at a given address using the command +@code{sbpa} (set breakpoint at address). When a breakpoint is set, +@code{run} will stop before executing the instruction at the given +address. Typing @code{run} again will resume program execution. Coming +back to our hello world example, we would have: + +@example +MIX > sbpa 3001 +Breakpoint set at address 3001 +MIX > run +Running ... +MIXAL HELLO WORLD +... stopped: breakpoint at line 8 (address 3001) +Elapsed time: 1 /Total program time: 1 (Total uptime: 23) +MIX > run +Running ... +... done +Elapsed time: 10 /Total program time: 11 (Total uptime: 33) +MIX > +@end example + +@cindex @code{sbp} +@cindex breakpoints +@noindent +Note that, since we compiled @file{hello.mixal} with debug info +enabled, the virtual machine is able to tell us the line in the +source file corresponding to the breakpoint we are setting. As a +matter of fact, you can directly set breakpoints at source code lines +using the command @code{sbp LINE_NO}, e.g. + +@example +MIX > sbp 4 +Breakpoint set at line 7 +MIX > +@end example + +@noindent +@code{sbp} sets the breakpoint at the first meaningful source code line; +thus, in the above example we have requested a breakpoint at a line +which does not correspond to a MIX instruction and the breakpoint is set +at the first line containing a real instruction after the given one. To +unset breakpoints, use @code{cbpa ADDRESS} and @code{cbp LINE_NO}, or +@code{cabp} to remove all currently set breakpoints. You can also set +conditional breakpoints, i.e., tell @code{mixvm} to interrupt program +execution whenever a register, a memory cell, the comparison flag or the +overflow toggle change using the commands @w{@code{sbp[rmco]}} +(@pxref{Debug commands}). + +@cindex @code{psym} +MIXAL lets you define symbolic constants, either using the @code{EQU} +pseudoinstruction or starting an instruction line with a label (which +assigns to the label the value of the current memory address). Each +MIXAL program has, therefore, an associated symbol table which you can +inspect using the @code{psym} command. For our hello world sample, you +will obtain the following output: + +@example +MIX > psym +START: 3000 +TERM: 19 +MSG: 3002 +MIX > +@end example + +Other useful commands for debugging are @code{strace} (which turns on +tracing of executed intructions), @code{pbt} (which prints a backtrace +of executed instructions) and @code{weval} (which evaluates +w-expressions on the fly). For a complete description of all available +MIX commands, @xref{mixvm}. + +@node Using mixguile, Using Scheme in mixvm and gmixvm, Running the program, Getting started +@section Using @code{mixguile} + +With @code{mixguile} you can run a MIX simulator embedded in a Guile +shell, that is, using Scheme functions and programs.

But, in case +you are wondering, this is only the beginning. You also have at your +disposal a whole Scheme interpreter, and you can, for instance, define +new functions combining the @code{mix-} and all other Scheme +primitives. In the next sections, you'll find examples of how to take +advantage of the Guile interpreter. + +@node Additional functions, Defining new functions, The mixguile shell, Using mixguile +@subsection Additional MIX Scheme functions + +The @code{mix-} function counterparts of the @code{mixvm} commands don't +return any value, and are evaluated only for their side-effects +(possibly including informational messages to the standard output and/or +error stream). When writting your own Scheme functions to manipulate the +MIX virtual machine within @code{mixguile} (@pxref{Defining new +functions}), you'll probably need Scheme functions returning the value +of the registers, memory cells and so on. Don't worry: @code{mixguile} +also offers you such functions. For instance, to access the (numerical) +value of a register you can use @code{mix-reg}: + +@example +guile> (mix-reg 'I2) +0 +guile> +@end example +@noindent +Note that, unlike @code{(mix-preg 'I2)}, the expression @code{(mix-reg +'I2)} in the above example evaluates to a Scheme number and does not +produce any side-effect: + +@example +guile> (number? (mix-reg 'I2)) +#t +guile> (number? (mix-preg 'I2)) +rI2: + 00 00 (0000) +#f +guile> +@end example + +In a similar fashion, you can access the memory contents using +@code{(mix-cell)}, or the program counter using @code{(mix-loc)}: + +@example +guile> (mix-cell 3000) +786957541 +guile> (mix-loc) +3002 +guile> +@end example + +Other functions returning the contents of the virtual machine components +are @code{mix-cmp} and @code{mix-over}, which eval to the value of the +comparison flag and the overflow toggle respectively. For a complete +list of these additional functions, @xref{mixguile}. + +In the next section, we'll see a sample of using these functions to +extend @code{mixguile}'s functionality. + +@node Defining new functions, Hook functions, Additional functions, Using mixguile +@subsection Defining new functions +@cindex Scheme functions + +Scheme is a powerful language, and you can use it inside @code{mixguile} +to easily extend the MIX interpreter's capabilities.

The following sections give you a tutorial on using +hook functions within @code{mixguile}. + +@menu +* Command hooks:: +* Break hooks:: +@end menu + +@node Command hooks, Break hooks, Hook functions, Hook functions +@subsubsection Command hooks + +In the previous section, we have seen how to extend @code{mixguile}'s +functionality through the use of user defined functions. Frequently, +you'll write new functions that improve in some way the workings of a +built-in @code{mixvm} command, following this pattern: + +@enumerate a +@item +Prepare the command execution +@item +Execute the desired command +@item +Perform post execution operations +@end enumerate + +We call the functions executed in step (a) @dfn{pre-hook}s, and those of +step @dfn{post-hook}s of the given command. @code{mixguile} lets you +specify pre- and post-hooks for any @code{mixvm} command using the +@code{mix-add-pre-hook} and @code{mix-add-post-hook} functions, which +take as arguments a symbol naming the command and a function to be +executed before (resp. after) the command. In other words, +@code{mixguile} will execute for you steps (a) and (c) above whenever +you eval (b). The hook functions must take a single argument, which is a +string list of the command's arguments. As an example, let us define the +following hooks for the @code{next} command: + +@example +(define next-pre-hook + (lambda (arglist) + (mix-slog #f))) + +(define next-post-hook + (lambda (arglist) + (display "Stopped at line ") + (display (mix-src-line-no)) + (display ": ") + (display (mix-src-line)) + (newline) + (mix-slog #t))) +@end example +@noindent +In these functions, we are using the function @code{mix-slog} to turn +off the informational messages produced by the virtual machine, since we +are providing our own ones in the post hook function. To install these +hooks, we would write: + +@example +(mix-add-pre-hook 'next next-pre-hook) +(mix-add-post-hook 'next next-post-hook) +@end example +@noindent +Assuming we have put the above expressions in @code{mixguile}'s +initialisation file, we would obtain the following results when +evaluating @code{mix-next}: + +@example +guile> (mix-next) +MIXAL HELLO WORLD +Stopped at line 6: HLT +guile> +@end example + +As a second, more elaborated, example, let's define hooks which print +the address and contents of a cell being modified using @code{smem}. The +hook functions could be something like this: + +@example +(define smem-pre-hook + (lambda (arglist) + (if (eq? (length arglist) 2) + (begin + (display "Changing address ") + (display (car arglist)) + (newline) + (display "Old contents: ") + (display (mix-cell (string->number (car arglist)))) + (newline)) + (error "Wrong arguments" arglist)))) + +(define smem-post-hook + (lambda (arglist) + (if (eq? (length arglist) 2) + (begin + (display "New contents: ") + (display (mix-cell (string->number (car arglist)))) + (newline))))) +@end example +@noindent +and we can install them using + +@example +(mix-add-pre-hook 'smem smem-pre-hook) +(mix-add-post-hook 'smem smem-post-hook) +@end example +@noindent +Aferwards, a sample execution of @code{mix-smem} would look like this: + +@example +guile> (mix-smem 2000 100) +Changing address 2000 +Old contents: 0 +New contents: 100 +guile> +@end example + +@cindex global hook + +You can add any number of hooks to a given command. They will be +executed in the same order as they are registered. You can also define +global post (pre) hooks, which will be called before (after) any +@code{mixvm} command is executed. Global hook functions must admit two +arguments, namely, a string naming the invoked command and a string list +of its arguments, and they are installed using the Scheme functions +@code{mix-add-global-pre-hook} and @code{mix-add-global-post-hook}. A +simple example of global hook would be: + +@example +guile> (define pre-hook + (lambda (cmd args) + (display cmd) + (display " invoked with arguments ") + (display args) + (newline))) +guile> (mix-add-global-pre-hook pre-hook) +ok +guile> (mix-pmem 120 125) +pmem invoked with arguments (120-125) +0120: + 00 00 00 00 00 (0000000000) +0121: + 00 00 00 00 00 (0000000000) +0122: + 00 00 00 00 00 (0000000000) +0123: + 00 00 00 00 00 (0000000000) +0124: + 00 00 00 00 00 (0000000000) +0125: + 00 00 00 00 00 (0000000000) +guile> +@end example + +Note that if you invoke @code{mixvm} commands within a global hook, its +associated command hooks will be run. Thus, if you have installed both +the @code{next} hooks described earlier and the global hook above, +executing @code{mix-next} will yield the following result: + +@example +guile> (mix-next 5) +next invoked with arguments (5) +slog invoked with arguments (off) +MIXAL HELLO WORLD +Stopped at line 7: MSG ALF "MIXAL" +slog invoked with arguments (on) +guile> +@end example + +Adventurous readers may see the above global hook as the beginning of a +command log utility or a macro recorder that saves your commands for +replay. + +@node Break hooks, , Command hooks, Hook functions +@subsubsection Break hooks + +@cindex break hook + +We have seen in the previous section how to associate hooks to command +execution, but they are not the whole story. You can also associate hook +functions to program interruption, that is, specify functions that +should be called every time the execution of a MIX program is stopped +due to the presence of a breakpoint, either explicit or +conditional. Break hooks take as arguments the line number and memory +address at which the break occurred. A simple hook that logs the line +and address of the breakpoint could be defined as: + +@example +(define break-hook + (lambda (line address) + (display "Breakpoint encountered at line ") + (display line) + (display " and address ") + (display address) + (newline))) +@end example +@noindent +and installed for explicit and conditional breakpoints using + +@example +(mix-add-break-hook break-hook) +(mix-add-cond-break-hook break-hook) +@end example +@noindent +after that, every time the virtual machine encounters a breakpoint, +@code{break-code} shall be evaluated for you@footnote{You may have +noticed that break hooks can be implemented in terms of command hooks +associated to @code{mix-run} and @code{mix-next}. As a matter of fact, +they @emph{are} implemented this way: take a look at the file +@file{@emph{install_dir}/share/mdk/mix-vm-stat.scm} if you are curious.}. + +@node Scheme scripts, , Hook functions, Using mixguile +@subsection Scheme scripts +@cindex Scheme script +@cindex non-interactive + +Another useful way of using @code{mixguile} is writing executable +scripts that perform a set of commands for you.

For instance, if you have +a very useful MIX program @file{foo.mix} which you want to run often, +you don't have to fire a MIX virtual machine, load and run it every +time; you can write a Scheme script instead: + +@example +#! /usr/bin/mixguile -s +!# +;;; runprimes: execute the primes.mix program + +;; load the file you want to run +(mix-load "../samples/primes") +;; execute it +(mix-run) +;; print the contents of registers +(mix-pall) +;; ... +@end example + +Just save the above script to a file named, say, @file{runtest}, make it +executable (@code{chmod +x runtest}), and, well, execute it from the +Unix shell: + +@example +$ ./runtest +Program loaded.

For additional +@code{mixguile} command line options, see @ref{Invoking mixguile}. + +@node Using Scheme in mixvm and gmixvm, , Using mixguile, Getting started +@section Using Scheme in @code{mixvm} and @code{gmixvm} +@cindex @code{scmf} + +In the previous section (@pxref{Using mixguile}) we have seen how the +Guile shell @code{mixguile} offers you the possibility of using Scheme +to manipulate a MIx virtual machine and extend the set of commands +offered by @code{mixvm} and @code{gmixvm}. This possibility is not +limited to the @code{mixguile} shell. Actually, both @code{mixvm} and +@code{gmixvm} incorporate an embedded Guile interpreter, and can +evaluate Scheme expressions.

Knuth uses an imaginary computer, the MIX, and its +associated machine-code and assembly languages to ilustrate the +concepts and algorithms as they are presented. + +The MIX's architecture is a simplified version of those found in real +CISC CPUs, and the MIX assembly language (MIXAL) provides a set of +primitives that will be very familiar to any person with a minimum +experience in assembly programming. The MIX/MIXAL definition is powerful +and complete enough to provide a virtual development platform for +writing quite complex programs, and close enough to real computers to be +worth using when learning programming techniques. At any rate, if you +want to learn or improve your programming skills, a MIX development +environment would come in handy. + +The @sc{mdk} package aims at providing such virtual development +environment on a GNU box. Thus, @sc{mdk} offers you a set of utilities +to simulate the MIX computer and to write, compile, run and debug MIXAL +programs. As of version @value{VERSION}, @sc{mdk} includes +the following programs: + +@table @code +@item mixasm +MIXAL assembler. Assembler which translates MIXAL source files into +programs that can be run (and debugged) by @code{mixvm}, @code{mixguile} +or @code{gmixvm}. +@item mixvm +MIX virtual machine.

These binary programs could be written by hand, but it is +easier to produce them compiling MIXAL source files, using the MIXAL +assembler @code{mixasm}. On the other hand, @code{mixguile} offers you +the possibility of manipulating a MIX virtual machine through a set of +Scheme functions, so that you can use this programming language to +interact with the virtual machine.

Conversely, @code{mixvm} and @code{gmixvm} contain +a Guile interpreter, and are able to use this same Scheme library, as +well as all the other Guile/Scheme primitives and any user defined +function. Therefore, you have at your disposal a powerful programming +language, Scheme, to extend the @sc{mdk} virtual machine emulators (see +@ref{Using Scheme in mixvm and gmixvm} for samples of how to do it). + +The following subsections describe available functions the MIX/Scheme +library. + +@menu +* mixvm wrappers:: Functions invoking mixvm commands. +* Hooks:: Adding hooks to mixvm commands. +* Additional VM functions:: Functions accessing the MIX virtual machine. +@end menu + +@node mixvm wrappers, Hooks, Scheme functions reference, Scheme functions reference +@subsection @code{mixvm} command wrappers + +For each of the @code{mixvm} commands listed in @ref{Commands}, there is +a corresponding Scheme function named by prefixing the command name with +@code{mix-} (e.g., @code{mix-load}, @code{mix-run} and so on). These +command wrappers are implemented using a generic command dispatching +function: + +@defun mixvm-cmd command argument +Dispatchs the given @var{command} to the MIX virtual appending the +provided @var{argument}. Both @var{command} and @code{argument} must be +strings. The net result is as writing "@var{command} @var{argument}" at +the @code{mixvm} or @code{gmixvm} command prompt. +@end defun + +For instance, you can invoke the @code{run} command at the @code{mixvm} +prompt in three equivalent ways: + +@example +MIX > run hello +MIX > (mix-run "hello") +MIX > (mixvm-cmd "run" "hello") +@end example +@noindent +(only the two last forms can be used at the @code{mixguile} prompt or +inside a Scheme script). + +The @code{mix-} functions evaluate to a unspecified value. If you want +to check the result of the last @code{mixvm} command invocation, use the +@code{mix-last-result} function: + +@defun mix-last-result +Returns @var{#t} if the last @code{mixvm} command invocation was +successful, @var{#f} otherwise. +@end defun +@noindent +Using this function, we could improve the script for running a program +presented in the previous section by adding error checking: + + +@example +#! /usr/bin/mixguile \ +-e main -s +!# + +;;; Execute a given program and print the registers. + +(define main + (lambda (args) + ;; load the file provided as a command line argument + (mix-load (cadr args)) + ;; execute it if mix-load succeeded + (if (mix-last-result) (mix-run)) + ;; print the contents of registers if the above commands succeded + (if (mix-last-result) (mix-pall)))) +@end example + +Please, refer to @ref{Commands} for a list of available commands. Given +the description of a @code{mixvm}, it is straightforward to use its +Scheme counterpart and, therefore, we shall not give a complete +description of these functions here. Instead, we will only mention those +wrappers that exhibit a treatment of their differing from that of their +command counterpart. + +@defun mix-preg [register] +@defunx mix-sreg register value +The argument @var{register} of these functions can be either a string or +a symbol representing the desired register. For instance, the following +invocations are equivalent: + +@example +(mix-preg 'I1) +(mix-preg "I1") +@end example +@end defun + +@defun mix-pmem from [to] +The command @code{pmem} takes a single argument which can be either a +cell number or a range of the form @code{FROM-TO}. This function takes +one argument to ask for a single memory cell contents, or two parameters +to ask for a range. For instance, the following commands are equivalent: + +@example +MIX > pmem 10-12 +0010: + 00 00 00 00 00 (0000000000) +0011: + 00 00 00 00 00 (0000000000) +0012: + 00 00 00 00 00 (0000000000) +MIX > (mix-pmem 10 12) +0010: + 00 00 00 00 00 (0000000000) +0011: + 00 00 00 00 00 (0000000000) +0012: + 00 00 00 00 00 (0000000000) +MIX > +@end example +@end defun + +@defun mix-sover #t|#f +The command @code{sover} takes as argument either the string @code{T} or +the string @code{F}, to set, respectively, the overflow toggle to true +or false. Its Scheme counterpart, @code{mix-sover}, takes as argument +a Scheme boolean value: @code{#t} (true) or @code{#f}. +@end defun + +For the remaining functions, you simply must take into account that when +the command arguments are numerical, the corresponding Scheme function +takes as arguments Scheme number literals. On the other hand, when the +command argument is a string, the argument of its associated Scheme +function will be a Scheme string. By way of example, the following +invocations are pairwise equivalent: + +@example +MIX > load ../samples/hello +MIX > (mix-load "../samples/hello") + +MIX > next 5 +MIX > (mix-next 5) +@end example + +@node Hooks, Additional VM functions, mixvm wrappers, Scheme functions reference +@subsection Hook functions + +Hooks are functions evaluated before or after executing a @code{mixvm} +command (or its corresponding Scheme function wrapper), or after an +explicit or conditional breakpoint is found during the execution of a +MIX program. The following functions let you install hooks: + +@defun mix-add-pre-hook command hook +Adds a function to the list of pre-hooks associated with the give +@var{command}. @var{command} is a string naming the corresponding @code{mixvm} +command, and @var{hook} is a function which takes a single argument: a +string list of the commands arguments. The following scheme code defines +a simple hook and associates it with the @code{run} command: + +@example +(define run-hook + (lambda (args) + (display "argument list: ") + (display args) + (newline))) +(mix-add-pre-hook "run" run-hook) +@end example + +Pre-hooks are executed, in the order they are added, before invoking the +corresponding command (or its associated Scheme wrapper function). +@end defun + +@defun mix-add-post-hook command hook +Adds a function to the list of pre-hooks associated with the give +@var{command}. The arguments have the same meaning as in +@code{mix-add-pre-hook}. +@end defun + +@defun mix-add-global-pre-hook hook +@defunx mix-add-global-post-hook hook +Global pre/post hooks are executed before/after any @code{mixvm} command +or function wrapper invocation. In this case, @var{hook} takes two +arguments: a string with the name of the command being invoked, and a +string list with its arguments. +@end defun + +@defun mix-add-break-hook hook +@defunx mix-add-cond-break hook +Add a hook funtion to be executed when an explicit (resp. conditional) +breakpoint is encountered during program execution. @var{hook} is a +function taking two arguments: the source line number where the hook has +occurred, and the current program counter value. The following code +shows a simple definition and installation of a break hook: + +@example +(define break-hook + (lambda (line address) + (display "Breakpoint at line ") (display line) + (display " and address ") (display address) + (newline))) +(mix-add-break-hook break-hook) +@end example + +Break hook functions are entirely implemented in Scheme using regular +post-hooks for the @code{next} and @code{run} commands. If you are +curious, you can check the Scheme source code at +@file{@emph{prefix}/share/mdk/mixguile-vm-stat.scm} (where @emph{prefix} +stands for your root install directory, usualy @code{/usr} or +@code{/usr/local}. +@end defun + + +See @ref{Hook functions} for further examples on using hook functions. + + +@node Additional VM functions, , Hooks, Scheme functions reference +@subsection Additional VM functions + +When writing non-trivial Scheme extensions using the MIX/Scheme library, +you will probably need to evaluate the contents of the virtual machine +components (registers, memory cells and so on). For instance, you may +need to store the contents of the @code{A} register in a variable. The +Scheme functions described so far are of no help: you can print the +contents of @code{A} using @code{(mix-preg 'A)}, but you cannot define a +variable containing the contents of @code{A}. To address this kind of +problems, the MIX/Scheme library provides the following additional +functions: + +@defun mixvm-status +@defunx mix-vm-status +Return the current status of the virtual machine, as a number +(@code{mixvm-status}) or as a symbol (@code{mix-vm-status}). Posible +return values are: +@multitable {aamixvmaastatusaa} {aamixvmastatusaaaaaaa} {return valuesaaaaaaaaaaaaaaaaaaaaaaaaaa} +@item @code{(mixvm-status)} @tab @code{(mix-vm-status)} @tab +@item 0 @tab MIX_ERROR @tab Loading or execution error +@item 1 @tab MIX_BREAK @tab Breakpoint encountered +@item 2 @tab MIX_COND_BREAK @tab Conditional breakpoint +@item 3 @tab MIX_HALTED @tab Execution terminated +@item 4 @tab MIX_RUNNING @tab Execution stopped after @code{next} +@item 5 @tab MIX_LOADED @tab Program successfully loaded +@item 6 @tab MIX_EMPTY @tab No program loaded +@end multitable +@end defun + +@defun mix-vm-error? +@defunx mix-vm-break? +@defunx mix-vm-cond-break? +@defunx mix-vm-halted? +@defunx mix-vm-running? +@defunx mix-vm-loaded? +@defunx mix-vm-empty? +Predicates asking whether the current virtual machine status is +@code{MIX_ERROR}, @code{MIX_BREAK}, etc. +@end defun + +@defun mix-reg register +@defunx mix-set-reg! register value +@code{mix-reg} evaluates to a number which is the contents of the +specified @var{register}. @code{mix-set-reg} sets the contents of the +given @var{register} to @var{value}. The register can be specified +either as a string (@code{"A"}, @code{"X"}, etc.) or as a symbol +(@code{'A}, @code{'X}, etc.). For instance, + +@example +guile> (mix-reg 'A) +2341 +guile> (mix-set-reg! "A" 2000) +ok +guile> (define reg-a (mix-reg 'A)) +guile> (display reg-a) +2000 +guile> +@end example +@end defun + +@defun mix-cell cell_no +@defunx mix-set-cell! cell_no value +Evaluate and set the contents of the memory cell number +@var{cell_no}. Both @var{cell_no} and @var{value} are Scheme numbers. +@end defun + +@defun mix-loc +Evaluates to the value of the location counter (i.e., the address of the +next instruction to be executed). +@end defun + +@defun mix-over +@defunx mix-set-over! #t|#f +@code{mix-over} evaluates to @code{#t} if the overflow toggle is set, +and to @code{#f} otherwise.

Execution is interrupted either when the specified +number of instructions have been fetched or a breakpoint is found, +whatever happens first. If run without arguments, one instruction is +executed. If @code{next} is invoked again after program execution +completion (i.e., after the @code{HLT} instruction has been found in a +previous run), the program counter is repositioned and execution starts +again from the beginning (as a matter of fact, a @code{load} command +preserving the currently set breakpoints is issued before resuming +execution). +@end deffn + +@deffn {debug command} sbp line_number +@deffnx {debug command} cbp line_no +Sets a breakpoint at the specified source file line number.

Thus, for our sample @file{hello.mixal} file: + +@example +* (1) +* hello.mixal: say 'hello world' in MIXAL (2) +* (3) +* label ins operand comment (4) +TERM EQU 19 the MIX console device number (5) + ORIG 1000 start address (6) +START OUT MSG(TERM) output data at address MSG (7) +... +@end example + +@noindent +trying to set a breakpoint at line 5, will produce the following result: + +@example +MIX > sbp 5 +Breakpoint set at line 7 +MIX > +@end example + +@noindent +since line 7 is the first one compiled into a MIX instruction (at +address 3000). + +The command @code{cbp} clears a (previously set) breakpoint at the given +source file line. +@end deffn + +@deffn {debug command} spba address +@deffnx {debug command} cbpa address +Sets a breakpoint at the given memory @var{address}.

Thus, in the program fragment + +@example +VAR EQU 2168 + ORIG 4000 +START LDA VAR +@end example + +@noindent +the symbol @code{VAR} stands for the value 2168, while @code{START} is +assigned the value 4000. The symbol table can be consulted from +the @code{mixvm} command line using @code{psym} followed by the name of +the symbol whose contents you are interested in. When run without +arguments, @code{psym} will print all defined symbols and their values. +@end deffn + +The virtual machine can also show you the instructions it is executing, +using the following commands: + +@deffn {debug command} strace [on|off] +@code{strace on} enables instruction tracing. When tracing is enabled, +each time the virtual machine executes an instruction (due to your +issuing a @code{run} or @code{next} command), it is printed in its +canonical form (that is, with all expressions evaluated to their +numerical values) and, if the program was compiled with debug +information, as it was originally typed in the MIXAL source +file. Instruction tracing is disabled with @code{strace off} +command. A typical tracing session could be like this: + +@example +MIX > strace on +MIX > next +3000: [OUT 3002,0(2:3)] START OUT MSG(TERM) +MIXAL HELLO WORLD +Elapsed time: 1 /Total program time: 1 (Total uptime: 1) +MIX > next +3001: [HLT 0,0] HLT +End of program reached at address 3002 +Elapsed time: 10 /Total program time: 11 (Total uptime: 11) +MIX > strace off +MIX > +@end example +@noindent +The executed instruction, as it was translated, is shown between square +brackets after the memory address, and, following it, you can see the +actual MIXAL code that was compiled into the executed instruction.

When you request an output operation on any other +(output) device, a file named according to the following table will be +created, and the specified MIX words will be +written to the file in binary form (for binary devices) or in ASCII (for +char devices). Files corresponding to input block devices should be +created and filled beforehand to be used by the MIX virtual machine (for +input-output devices this creation can be accomplished by a MIXAL +program writing to the device the required data, or, if you prefer, with +your favourite editor). The device files are stored, by default, in the +directory @file{~/.mdk}; this location can be changed using the +@code{mixvm} command @code{devdir} (@pxref{Configuration commands}). + +@multitable {the device name} { xx-xx } {filename[x-x].dev} {bin i/o/char } +@item @emph{Device} @tab @emph{No.} @tab @emph{filename} @tab @emph{type and block size} +@item Tape @tab 0-7 @tab @file{tape[0-7].dev} @tab bin i/o - 100 words +@item Disks @tab 8-15 @tab @file{disk[0-7].dev} @tab bin i/o - 100 words +@item Card reader @tab 16 @tab @file{cardrd.dev} @tab char in - 16 words +@item Card writer @tab 17 @tab @file{cardwr.dev} @tab char out - 16 words +@item Line printer @tab 18 @tab @file{printer.dev} @tab char out - 24 words +@item Terminal @tab 19 @tab @code{stdin/stdout} @tab char i/o - 14 words +@item Paper tape @tab 20 @tab @file{paper.dev} @tab char in - 14 words +@end multitable + +Devices of type @i{char} are stored as ASCII files, using one line per +block. For instance, since the card reader has blocks of size 16, that +is, 80 characters, it will be emulated by an ASCII file consisting of +lines with length 80. If the reader finds a line with less than the +required number of characters, it pads the memory with zeroes (MIX +character 'space') to complete the block size. + +Note that the virtual machine automatically converts between the MIX and +ASCII character encodings, so that you can manipulate char device files +with any ASCII editor. In addition, the reader is not case-sensitive, +i.e., it automatically converts lowercase letters to their uppercase +counterparts (since the MIX character set does not include the former). + +The typewriter (device no. 19) lets you use the standard input and +output in your MIXAL programs.

Note that a +MIX byte can be then represented as 6 bits, instead of the common 8 bits +for a @emph{regular} byte. Unless otherwise stated, we shall use the +word @dfn{byte} to refer to a MIX 6-bit byte. + +A MIX @dfn{word} is defined as a set of 5 bytes plus a sign. The bytes +within a word are numbered from 1 to 5, being byte number one the most +significant one. The sign is denoted by index 0. Graphically, + +@example + ----------------------------------------------- +| 0 | 1 | 2 | 3 | 4 | 5 | + ----------------------------------------------- +| +/- | byte | byte | byte | byte | byte | + ----------------------------------------------- +@end example +@noindent +Sample MIX words are @samp{- 12 00 11 01 63} and @samp{+ 12 11 34 43 +00}. + +You can refer to subfields within a word using a @dfn{field +specification} or @dfn{fspec} of the form ``(@var{L}:@var{R})'', where +@var{L} denotes the first byte, and @var{R} the last byte of the +subfield. +When @var{L} is zero, the subfield includes the word's +sign. An fspec can also be represented as a single value @code{F}, given +by @code{F = 8*L + R} (thus the fspec @samp{(1:3)}, denoting the first +three bytes of a word, is represented by the integer 11). + +The MIX computer stores information in @dfn{registers}, that can store +either a word or two bytes and sign (see below), and @dfn{memory cells}, +each one containing a word. Specifically, the MIX computer has 4000 +memory cells with addresses 0 to 3999 (i.e., two bytes are enough to +address a memory cell) and the following registers: + +@cindex rA +@cindex rX +@cindex rJ +@cindex rIn +@cindex register + +@table @asis +@item @code{rA} +A register. General purpose register holding a word. Usually its +contents serves as the operand of arithmetic and storing instructions. +@item @code{rX} +X register. General purpose register holding a word. Often it acts as an +extension or a replacement of @samp{rA}. +@item @code{rJ} +J (jump) register.

These six registers can store a signed two-byte +value.

In this manual, this toggle is denoted @sc{ov}. +@item +A @dfn{comparison indicator} (having three values: @dfn{EQUAL}, +@dfn{GREATER} or @dfn{LESS}). In this manual, this indicator is denoted +@sc{cm}, and its possible values are abbreviated as @dfn{E}, @dfn{G} and +@dfn{L}. +@item +Input-output block devices. Each device is labelled as @code{un}, where +@code{n} runs from 0 to 20. In Knuth's definition, @code{u0} through +@code{u7} are magnetic tape units, @code{u8} through @code{15} are disks +and drums, @code{u16} is a card reader, @code{u17} is a card writer, +@code{u18} is +a line printer and, @code{u19} is a typewriter terminal, and @code{u20}, +a paper tape. Our implementation maps these devices to disk files, +except for @code{u19}, which represents the standard output. +@end itemize + +As noted above, the MIX computer communicates with the external world by +a set of input-output devices which can be ``connected'' to it.

The other bytes of the memory cell retain their +values. Thus, if prior to the instruction execution we have + +@example +[1200] = - 20 21 22 23 24 +[rA] = + 01 02 03 04 05 +@end example +@noindent +we will end up with + +@example +[1200] = - 20 04 05 23 24 +[rA] = + 01 02 03 04 05 +@end example + +As a second example, @samp{ST2 1000(0)} will set the sign of +@samp{[1000]} to that of @samp{[rI2]}. + +@node Arithmetic operators, Address transfer operators, Storing operators, MIX instruction set +@comment node-name, next, previous, up +@subsubsection Arithmetic operators +@cindex arithmetic operators + +The following instructions perform arithmetic operations between rA and +rX register and memory contents. + +@ftable @code +@item ADD +Add and set OV if overflow.

In multiplication +and division, the register @samp{X} comes into play as a right-extension +of the register @samp{A}, so that we are able to handle 10-byte numbers +whose more significant bytes are those of @samp{rA} (the sign of this +10-byte number is that of @samp{rA}: @samp{rX}'s sign is ignored). + +Addition and substraction of MIX words can give rise to overflows, since +the result is stored in a register with room to only 5 bytes (plus +sign).

You cannot directly modify the contents +of this internal register with a load instruction: after fetching the +current instruction from memory, it is automatically increased in one +unit by the MIX. However, there is a set of instructions (which we call +jump instructions) which can alter the contents of the location counter +provided some condition is met. When this occurs, the value of the next +instruction address that would have been fetched in the absence of the +jump is stored in @samp{rJ} (except for @code{JSJ}), and the location +counter is set to the value of @samp{M} (so that the next instruction is +fetched from this new address).

Of course, this +execution time will be a function of the input size, and the answer to +our question is commonly given as the asymptotic behaviour as a +function of the input size. At any rate, to compute this asymptotic +behaviour, we need a measure of how long execution of a single +instruction takes in our (virtual) CPU. Therefore, each MIX +instruction will have an associated execution time, given in arbitrary +units (in a real computer, the value of this unit will depend on the +hardware configuration).

As we have shown, each instruction is represented by a +word which is fetched from memory and executed by the MIX virtual +CPU. As is the case with real computers, the MIX knows how to decode +instructions in binary format (the so--called machine language), but a +human programmer would have a tough time if she were to write her +programs in machine language. Fortunately, the MIX computer can be +programmed using an assembly language, MIXAL, which provides a symbolic +way of writing the binary instructions understood by the imaginary MIX +computer. If you have used assembler languages before, you will find +MIXAL a very familiar language. MIXAL source files are translated +to machine language by a MIX assembler, which produces a binary file (the +actual MIX program) which can be directly loaded into the MIX memory and +subsequently executed. + +In this section, we describe MIXAL, the MIX assembly language. The +implementation of the MIX assembler program and MIX computer simulator +provided by @sc{mdk} are described later on (@pxref{Getting started}). + +@menu +* Basic structure:: Writing basic MIXAL programs. +* MIXAL directives:: Assembler directives. +* Expressions:: Evaluation of expressions. +* W-expressions:: Evaluation of w-expressions. +* Local symbols:: Special symbol table entries. +* Literal constants:: Specifying an immediate operand. +@end menu + +@node Basic structure, MIXAL directives, MIXAL, MIXAL +@comment node-name, next, previous, up +@subsection Basic program structure + +The MIX assembler reads MIXAL files line by line, producing, when +required, a binary instruction, which is associated to a predefined +memory address. To keep track of the current address, the assembler +maintains an internal location counter which is incremented each time an +instruction is compiled. In addition to MIX instructions, you can +include in MIXAL file assembly directives (or pseudoinstructions) +addressed at the assembler itself (for instance, telling it where the +program starts and ends, or to reposition the location counter; see below). + +MIX instructions and assembler directives@footnote{We shall call them, +collectively, MIXAL instructions.} are written in MIXAL (one per +source file line) according to the following pattern: + +@example +[LABEL] MNEMONIC [OPERAND] [COMMENT] +@end example + +@noindent +where @samp{OPERAND} is of the form + +@example +[ADDRESS][,INDEX][(MOD)] +@end example + +Items between square brackets are optional, and + +@table @code +@item LABEL +is an alphanumeric identifier (a @dfn{symbol}) which gets the current +value of the location counter, and can be used in subsequent +expressions, +@item MNEMONIC +is a literal denoting the operation code of the instruction +(e.g. @code{LDA}, @code{STA}; see @pxref{MIX instruction set}) or an +assembly pseudoinstruction (e.g. @code{ORG}, @code{EQU}), +@item ADDRESS +is an expression evaluating to the address subfield of the instruction, +@item INDEX +is an expression evaluating to the index subfield of the instruction, which +defaults to 0 (i.e., no use of indexing) and can only be used when +@code{ADDRESS} is present, +@item MOD +is an expression evaluating to the mod subfield of the instruction. Its +default value, when omitted, depends on @code{OPCODE}, +@item COMMENT +any number of spaces after the operand mark the beggining of a comment, +i.e. any text separated by white space from the operand is ignored by +the assembler (note that spaces are not allowed within the +@samp{OPERAND} field). +@end table + +Note that spaces are @emph{not} allowed between the @code{ADDRESS}, +@code{INDEX} and @code{MOD} fields if they are present. White space is +used to separate the label, operation code and operand parts of the +instruction@footnote{In fact, Knuth's definition of MIXAL restricts the +column number at which each of these instruction parts must start. The +MIXAL assembler included in @sc{mdk}, @code{mixasm}, does not impose +such restriction.}. + +We have already listed the mnemonics associated will each MIX +instructions; sample MIXAL instructions representing MIX instructions +are: +@example +HERE LDA 2000 HERE represents the current location counter + LDX HERE,2(1:3) this is a comment + JMP 1234 +@end example + +@node MIXAL directives, Expressions, Basic structure, MIXAL +@comment node-name, next, previous, up +@subsection MIXAL directives + +MIXAL instructions can be either one of the MIX machine instructions +(@pxref{MIX instruction set}) or one of the following assembly +pseudoinstructions: + +@ftable @code +@item ORIG +Sets the value of the memory address to which following instructions +will be allocated after compilation. +@item EQU +Used to define a symbol's value, e.g. @w{@code{SYM EQU 2*200/3}}. +@item CON +The value of the given expression is copied directly into the current +memory address. +@item ALF +Takes as operand five characters, constituting the five bytes of a word +which is copied directly into the current memory address. +@item END +Marks the end of the program. Its operand gives the start address for +program execution. +@end ftable + +The operand of @code{ORIG}, @code{EQU}, @code{CON} and @code{END} can be +any expression evaluating to a constant MIX word, i.e., either a simple +MIXAL expression (composed of numbers, symbols and binary operators, +@pxref{Expressions}) or a w-expression (@pxref{W-expressions}). + +All MIXAL programs must contain an @code{END} directive, with a twofold +end: first, it marks the end of the assembler job, and, in the second +place, its (mandatory) operand indicates the start address for the +compiled program (that is, the address at which the virtual MIX machine +must begin fetching instructions after loading the program). It is also +very common (although not mandatory) to include at least an @code{ORIG} +directive to mark the initial value of the assembler's location counter +(remember that it stores the address associated with each compiled MIX +instruction). Thus, a minimal MIXAL program would be + +@example + ORIG 2000 set the initial compilation adress + NOP this instruction will be loaded at adress 2000 + HLT and this one at address 2001 + END 2000 end of program; start at address 2000 +this line is not parsed by the assembler +@end example +@noindent +The assembler will generate two binary instructions (@code{NOP} (@w{+ 00 +00 00 00 00}) and @code{HLT} (+ 00 00 02 05)), which will be loaded at +addresses 2000 and 2001. Execution of the program will begin at address +2000. Every MIXAL program should also include a @code{HLT} instruction, +which will mark the end of program execution (but not of program +compilation). + +The @code{EQU} directive allows the definition of symbolic names for +specific values. For instance, we could rewrite the above program as +follows: + +@example +START EQU 2000 + ORIG START + NOP + HLT + END START +@end example +@noindent +which would give rise to the same compiled code. Symbolic constants (or +symbols, for short) can also be implicitly defined placing them in the +@code{LABEL} field of a MIXAL instruction: in this case, the assembler +assigns to the symbol the value of the location counter before compiling +the line. Hence, a third way of writing our trivial program is + +@example + ORIG 2000 +START NOP + HLT + END START +@end example + +The @code{CON} directive allows you to directly specify the contents of +the memory address pointed by the location counter. For instance, when +the assembler encounters the following code snippet + +@example + ORIG 1150 + CON -1823473 +@end example +@noindent +it will assign to the memory cell number 1150 the contents @w{- 00 06 61 +11 49} (which corresponds to the decimal value -1823473). + +Finally, the @code{ALF} directive let's you specify the memory contents +as a set of five (optionally quoted) characters, which are translated by +the assembler to their byte values, conforming in that way the binary +word that is to be stored in the corresponding memory cell. This +directive comes in handy when you need to store printable messages in a +memory address, as in the following example @footnote{In the original +MIXAL definition, the @code{ALF} argument is not quoted. You can write +the operand (as the @code{ADDRESS} field) without quotes, but, in this +case, you must follow the alignment rules of the original MIXAL +definition (namely, the @code{ADDRESS} must start at column 17).}: + +@example + OUT MSG MSG is not yet defined here (future reference) +MSG ALF "THIS " MSG gets defined here + ALF "IS A " + ALF "MESSA" + ALF "GE. " +@end example +@noindent +The above snippet also shows the use of a @dfn{future reference}, that +is, the usage of a symbol (@code{MSG} in the example) prior of its actual +definition. The MIXAL assembler is able to handle future references +subject to some limitations which are described in the following section +(@pxref{Expressions}). + +@cindex comments + +Any line starting with an asterisk is treated as a comment and ignored +by the assembler. + +@example +* This is a comment: this line is ignored. + * This line is an error: * must be in column 1. +@end example + +As noted in the previous section, comments can also be located after the +@code{OPERAND} field of an instruction, separated from it by white +space, as in + +@example +LABEL LDA 100 This is also a comment +@end example + +@node Expressions, W-expressions, MIXAL directives, MIXAL +@comment node-name, next, previous, up +@subsection Expressions +@cindex operator +@cindex binary operator +@cindex unary operator +The @code{ADDRESS}, @code{INDEX} and @code{MOD} fields of a MIXAL +instruction can be expressions, formed by numbers, identifiers and +binary operators (@code{+ - * / // :}). @code{+} and @code{-} can also +be used as unary operators. Operator precedence is from left to right: +there is no other operator precedence rule, and parentheses cannot be +used for grouping. A stand-alone asterisk denotes the current memory +location; thus, for instance, + +@example + 4+2** +@end example + +@noindent +evaluates to 6 (4 plus 2) times the current memory location. White space +is not allowed within expressions. + +The special binary operator @code{:} has the same meaning as in fspecs, +i.e., + +@example +A:B = 8*A + B +@end example +@noindent +while @code{A//B} stands for the quotient of the ten-byte number @w{@code{A} 00 +00 00 00 00} (that is, A right-padded with 5 null bytes or, what amounts +to the same, multiplied by 64 to the fifth power) divided by +@code{B}. Sample expressions are: + +@example +18-8*3 = 30 +14/3 = 4 +1+3:11 = 4:11 = 43 +1//64 = (01 00 00 00 00 00)/(00 00 00 01 00) = (01 00 00 00 00) +@end example +@noindent +Note that all MIXAL expressions evaluate to a MIX word (by definition). + +All symbols appearing within an expression must be previously defined. Future +references are only allowed when appearing standalone (or modified by +an unary operator) in the @code{ADDRESS} part of a MIXAL instruction, +e.g. + +@example +* OK: stand alone future reference + STA -S1(1:5) +* ERROR: future reference in expression + LDX 2-S1 +S1 LD1 2000 +@end example + +@node W-expressions, Local symbols, Expressions, MIXAL +@comment node-name, next, previous, up +@subsection W-expressions +@cindex w-expressions + +Besides expressions, as described above (@pxref{Expressions}), the MIXAL +assembler is able to handle the so called @dfn{w-expressions} as the +operands of the directives @code{ORIG}, @code{EQU}, @code{CON} and +@code{END} (@pxref{MIXAL directives}). The general form of a +w-expression is the following: + +@example + WEXP = EXP[(EXP)][,WEXP] +@end example +@noindent +where @code{EXP} stands for an expression and square brackets denote +optional items. Thus, a w-expression is made by an expression, followed +by an optional expression between parenthesis, followed by any number +of similar constructs separated by commas. Sample w-expressions are: + +@example +2000 +235(3) +S1+3(S2),3000 +S1,S2(3:5),23 +@end example + +W-expressions are evaluated from left to right as follows: + +@itemize +@item +Start with an accumulated result @samp{w} equal to 0. +@item +Take the first expression of the comma-separated list and evaluate +it. For instance, if the w-expression is @samp{S1+2(2:4),2000(S2)}, we +evaluate first @samp{S1+2}; let's suppose that @samp{S1} equals +265230: then @samp{S1+2 = 265232 = + 00 01 00 48 16}. +@item +Evaluate the expression within parenthesis, reducing it to an f-spec +of the form @samp{L:R}. In our previous example, the expression +between parenthesis already has the desired form: 2:4. +@item +Substitute the bytes of the accumulated result @samp{w} designated by +the f-spec using those of the previous expression value. In our sample, +@samp{w = + 00 00 00 00 00}, and we must substitute bytes 2, 3 and 4 of +@samp{w} using values from 265232. We need 3 bytes, and we take the +least significant ones: 00, 48, and 16, and insert them in positions +2, 3 and 4 of @samp{w}, obtaining @samp{w = + 00 00 48 16 00}. +@item +Repeat this operation with the remaining terms, acting on the new +value of @samp{w}. In our example, if, say, @samp{S2 = 1:1}, we must +substitute the first byte of @samp{w} using one byte (the least +significant) from 2000, that is, 16 (since 2000 = + 00 00 00 31 16) +and, therefore, we obtain @samp{w = + 16 00 48 16 00}; summing up, we +have obtained @samp{265232(1:4),2000(1:1) = + 16 00 48 16 00 = +268633088}. +@end itemize + +As a second example, in the w-expression +@example +1(1:2),66(4:5) +@end example +@noindent +we first take two bytes from 1 (00 and 01) and store them as bytes 1 and +2 of the result (obtaining @w{@samp{+ 00 01 00 00 00}}) and, afterwards, +take two bytes from 66 (01 and 02) and store them as bytes 4 and 5 of +the result, obtaining @w{@samp{+ 00 01 00 01 02}} (262210). The process +is repeated for each new comma-separated example. For instance: + +@example +1(1:1),2(2:2),3(3:3),4(4:4) = 01 02 03 04 00 +@end example + +As stated before, w-expressions can only appear as the operands of MIXAL +directives taking a constant value (@code{ORIG}, @code{EQU}, @code{CON} +and @code{END}). Future references are @emph{not} allowed within +w-expressions (i.e., all symbols appearing in a w-expression must be +defined before it is used). + +@node Local symbols, Literal constants, W-expressions, MIXAL +@comment node-name, next, previous, up +@subsection Local symbols +@cindex local symbols + +Besides user defined symbols, MIXAL programmers can use the so called +@dfn{local symbols}, which are symbols of the form @code{[1-9][HBF]}. A +local symbol @code{nB} refers to the address of the last previous +occurrence of @code{nH} as a label, while @code{nF} refers to the next +@code{nH} occurrence. Unlike user defined symbols, @code{nH} can appear +multiple times in the @code{LABEL} part of different MIXAL +instructions. The following code shows an instance of local symbols' +usage: + +@example +* line 1 +1H LDA 100 +* line 2: 1B refers to address of line 1, 3F refers to address of line 4 + STA 3F,2(1B//2) +* line 3: redefinition of 1H +1H STZ +* line 4: 1B refers to address of line 3 +3H JMP 1B +@end example + +Note that a @code{B} local symbol never refers to a definition in its +own line, that is, in the following program: + +@example + ORIG 1999 +ST NOP +3H EQU 69 +3H ENTA 3B local symbol 3B refers to 3H in previous line + HLT + END ST +@end example +@noindent +the contents of @samp{rA} is set to 69 and @emph{not} to 2001.
