 New versions of Modula-2 compiler for MIPS, VAX available

The Western Research Laboratory of Digital Equipment Corporation is
pleased to announce the availability of a new version of their
Modula-2 compiler for VAXes running Ultrix or BSD, and for MIPS-based
DECstations running Ultrix 4.2.  (There are some code generation
problems in the MIPS compiler tools distributed with Ultrix 4.1 and
earlier systems.)

New in this release are support for the following modules described
in Wirth's book: InOut, MathLib0, RealInOut, Terminal, and TextIO.
These were contributed by Philip A. Nelson.  And the MIPS compiler
has been brought up to date with the VAX compiler, so the two
compilers now accept the same language.

The compiler was designed and built by Michael L.  Powell, and
originally released in 1984.  Joel McCormack sped the compiler up,
fixed lots of bugs, and swiped/wrote a User's Manual.  Len Lattanzi
ported the compiler to the MIPS.

The compiler generates better code than most compilers for the VAX.
The error messages are quite a bit better than those from the Ultrix
C compiler and the compile time is about the same as cc and gcc.
Further, the compiler includes an intermodule checker that uses
fine-grained dependencies rather than timestamps, so you can modify
definition modules in upward-compatible ways without recompiling
the world.

The compiler includes several extensions.  The most notable are:
provisions for interfacing with procedures and data types written in
other languages like C and Pascal (a definition module for the X11
C library is included); dynamic array variables, subarray parameters,
and multi-dimensional open array parameters; inline procedures;
complete support for the LONGFLOAT type; and a pseudo-module
providing a type-checked interface to the C library I/O routines.

The VAX portion of the release includes a Pascal compiler that
accepts a language almost identical to Berkeley Pascal.  (Procedure
parameters are not supported, and record layout and parameter passing
conventions are somewhat different.)  The VAX portion of the release
also includes a program that does most of the translation of Berkeley
Pascal programs into Modula-2.

The compiler is available for anonymous ftp from gatekeeper.dec.com,
in the 5.7 megabyte compressed tar file /pub/DEC/Modula-2/m2.tar.Z.
Once you have copied this file into a directory called m2, you can
uncompress it and untar it, like:

                  uncompress m2.tar.Z
                  tar xf m2.tar

This will create several files and three additional directories,
m2-src, m2-vax and m2-mips.  (The uncompressed tar file is about 13.8
megabytes, and the untarred files will take up about 14 megabytes, so
make sure you have lots of disk space.)

From there, read the m2-src/README file, and the
m2-vax/doc/installation.f file.

The compiler is available to DEC sites over DECNET at
decwrl::/pub/DEC/Modula-2/m2.tar.Z.

The compiler is also available by magnetic tape.  Please specify
whether you would like a 9-track, 1600 bpi tape, or a TK50 tape.

of the compiler to educational institutions.  The license agreement
