*Version 0.2
** mixvm provides virtual execution time statistics after each
invocation of run or next.
** mixvm can trace instructions as they are executed. tron/troff
commands turn off/off instruction tracing.
** mixvm accepts a new command, w2d, which computes the
decimal value of a MIX word given as a series of
bytes (e.g. - 01 00 34 32 22).
** symbols can be defined at the mixvm prompt with the
new command ssym.
** mixvm accepts a new command, weval, which allows the
evaluation of MIXAL w-expressions.
** expressions containing strings of successive '*' are now
correctly evaluated.
** When using block devices in mixvm, the buffers are now
flushed after each OUT operation.
*Version 0.1.1 (18/11/00)
** MDK is now compilable in rpm-based linuxes.
** MDK fully compliant with Knuth's specification. In particular,
local symbols are now properly handled in special cases such as
3H ORIG 3B
instructions. See samples/stress{1,2}.mixal.
** Future references affected by unary minus are accepted
with a warning (they are banned in Knuth's specification).
Also future refs in EQU directives are now properly handled.
See samples/stress{3,4}.mixal.
** When mixvm executes a program and reaches the end of the
available memory without encountering a HALT instruction,
it halts anyway.
*Version 0.1 (31/10/00)
** Initial version
