Modula-2 System
~~~~~~~~~~~~~~~

The Modula-2 compiler supports Modula-2 as defined in the 3rd edition
of Wirth's Programming in Modula-2.
Older versions of Modula-2 are supported, too.
The compiler is derived from the Lilith-Modula-2 compiler developed by
N. Wirth.

Environment:

o	The library is written in Modula-2.
	Interfaces to C are neither supported nor necessary.
o	The design of input/output modules is very close to stdio(3) of C.
o	Windows -- allows screen-oriented input/output (like curses(3)).
o	All system calls are possible - incl. signal handling.
o	Makefile generator -- supports multiple program modules and
	libraries.
o	Modula-2 source level debugger - supports even coroutines and
	signal handling.
o	mtags -- generation of tags (like ctags(1)).
o	mprof -- execution profiling (like prof(1)).

Software products ported to the Modula-2 system:

o	LIDAS database and Modula/R (a Modula-2 extension towards
	relational databases). Currently not available for SUN 3.
o	Modula--Prolog - an integrated Prolog-system.
o	myacc - a public domain version of yacc was modified to
	produce code for Modula-2.
o	alex and coco -- compiler construction tools from
	University of Linz.

These software products are available, too,
provided you have a source licence for the original product
(exception: myacc is public domain).

The Modula-2 system is available for:

	Concurrent Computer Series 3200 / XELOS
	Nixdorf Targon/31
	SUN 3
	SPARCv8 / Solaris 2.x

modula-2.2.1.tar.gz	Modula-2 distribution for Sun3 and SunOS 4.*;
			all sources are included.
modula-2.2.1.tar.gz.part?
			modula-2.2.1.tar.gz divided into 256kb partitions
modula-2.1.5.tar.Z	last release for SunOS versions before 4.0.
windows.tar.Z		Windows library (is part of modula-2.1.5.tar.Z).
			this windows library is based on termcap --
			the window library of modula-2.2.1.tar.gz is based
			on terminfo.
myacc.tar.Z		Modula-2 LALR(1) parser generator, sources are in C.

SunOS.4.1-problem	SunOS 4.1 introduces a new bug into /bin/as,
			which is currently not fixed by the modula-2 compiler.
			This files contains some instructions in case you
			have SunOS 4.1

gas-1.36.tar.Z		GNU assembler. The Modula-2 compiler of
			version 2.1.5 and 2.2.1 produces code
			acceptable for gas.  gas is needed for SunOS
			4.1.  If you have gas-1.35 it will probably
			work.  Newer versions of gas do not work for
			the Modula-2 system.
