M. 1. Alternative name for {MUMPS}. 2. A {C}-like language from {Silicon Compiler Systems} for multilevel {hardware description}. It is currently available in the {GDT} package from {Mentor Graphics}. [{Jargon File}] (1994-10-26) 3. The abbreviated for of {mega-}. (1995-01-10) m2. A {Modula-2} {compiler} for {VAX} and {MIPS}. A {Pascal} compiler for VAX is also included. The Pascal compiler accepts a language that is almost identical to {Berkeley Pascal}. It was originally designed and built by Michael L. Powell in 1984. Joel McCormack made it faster, fixed lots of bugs, and swiped/wrote a User's Manual. Len Lattanzi ported it to the MIPS. It has the following extensions: {foreign function} and data interface, {dynamic array} variables, {subarray parameter}s, multi-dimensional {open array parameter}s, {inline procedure}s, longfloat type, type-checked interface to {C} library I/O routines. It runs on {VAX} ({Ultrix}, {BSD}) and {MIPS} ({Ultrix}). {(ftp://gatekeeper.dec.com/pub/DEC/Modula-2/m2.tar.Z)}. E-mail: . (1992-07-06) M2toM3. A simple {Modula-2} to {Modula-3} translator by Peter Klein which covers most of the syntactic differences between those languages. No context sensitive analysis is done, so WITH statements, local {modules}, {enumeration type} literals and {variant RECORD}S have to be dealt with by hand. Part of the {Sun} Modula 2 library is emulated by the Modula 3 library. Version 1.01. {(ftp://martha.informatik.rwth-aachen.de/pub/Modula3)}. (1992-12-01) M3. A {macro} processor, forerunner of {M4}, for the {AP-3} {minicomputer}. m4. A {macro} processor for {Unix} and {GCOS} which is more flexible than {cpp}. m4 copies its input to the output, expanding macros which can be either built-in or user-defined. m4 has built-in functions for including files, running {Unix} commands, doing integer arithmetic, manipulating text in various ways and recursing. m4 can be used either as a {front-end} to a compiler or as a stand-alone tool. {sendmail}'s configuration file (/etc/sendmail.cf) is writen in m4 macros. There is a {GNU m4 v1.1 (ftp://gnu.org/pub/gnu/m4-1.0.tar.Z)} by Francois Pinard and a {public domain} version by Ozan Yigit and Richard A. O'Keefe (FTP from any {386BSD}, {NetBSD} or {FreeBSD} archive). A {Macintosh} version is {here (ftp://nic.switch.ch/pub/software/mac/src/mpw-c/)}. See also {m3}, {m5}. ["The M4 Macro Processor", Kernighan & Ritchie, Jul 1977]. M5. Macro processor, a generalisation of {M4} by A. Dain, U Cincinnati, 1992. For Unix and DOS. {(ftp://thor.exe.u.edu/pub/dain/m5)}. ma. The {country code} for Morocco. (1999-01-27) MAC. 1. {Media Access Control}. 2. Early system on {Ferranti} {Mercury}. Listed in CACM 2(5):16 (May 1959). Mac. {Macintosh} Mac-1. The {assembly language} used in the book cited below. See {Mic-1}. ["Structured Computer Organization", A.S. Tanenbaum, 3rd Edition, P-H 1989, Sect. 4.3]. (1996-04-07)
