+At this point, you have entered a Scheme read-eval-print loop (REPL)

+You get the idea: you have at your disposal all the @code{mixvm} and
+@code{gmixvm} commands by means of @code{mix-} functions. 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

+primitives. In the next sections, you'll find examples of how to take

+@subsection Definining 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. For example, you
+can easily define a function that loads a file, prints its name,
+executes it and, finally, shows the registers contents, all in one shot:
+
+@example
+guile> (define my-load-and-run @key{RET}
+ (lambda (file) @key{RET}
+ (mix-load file) @key{RET}
+ (display "File loaded: ") @key{RET}
+ (mix-pprog) @key{RET}
+ (mix-run) @key{RET}
+ (mix-preg))) @key{RET}
+guile>
+@end example
+@noindent
+and use it to run your programs:
+
+@example
+guile> (my-load-and-run "hello")
+Program loaded. Start address: 3000
+File loaded: hello.mix
+Running ...
+MIXAL HELLO WORLD
+... done

+rI5: + 00 00 (0000) rI6: + 00 00 (0000)
+guile>
+@end example
+
+
+Or, maybe, you want a function which sets a breakpoint at a specified
+line number before executing it:
+
+@example
+guile> (define my-load-and-run-with-bp
+ (lambda (file line)
+ (mix-load file)
+ (mix-sbp line)
+ (mix-run)))
+guile> (my-load-and-run-with-bp "samples/primes" 10)
+Program loaded. Start address: 3000
+Breakpoint set at line 10
+Running ...
+... stopped: breakpoint at line 10 (address 3001)
+Elapsed time: 1 /Total program time: 1 (Total uptime: 45)
+guile>
+@end example
+
+As you can see, the possibilities are virtually unlimited. Of course,
+you don't need to type a function definition each time you start
+@code{mixguile}. You can write it in a file, and load it using Scheme's
+@code{load} function. For instance, you can create a file named, say,
+@file{functions.scm} with the contents:
+
+@example
+(define my-load-and-run-with-bp
+ (lambda (file line)
+ (mix-load file)
+ (mix-sbp line)
+ (mix-run)))
+@end example
+
+and load it at the @code{mixguile} prompt:
+
+@example
+guile> (load "functions.scm")
+@end example
+
+
+
+As a third example, the following function loads a program, runs it and
+prints the contents of the memory between the program's start and end
+addresses:
