1) What is comp.lang.modula2?
comp.lang.modula2 is a forum for the discussion of the Modula-2 programming
language and related topics. Prominent "related topics" have been the Oberon
languages. The newsgroup is gated to the FidoNet echo conference MODULA-2.
Folk with only Internet E-Mail access can participate in the discussion by
joining the INFO-M2 mailing list. To do this, send an E-Mail message to
listserv@ucf1vm.cc.ucf.edu, with the following in the message body:
subscribe info-M2 yourFirstname yourLastName
This server also has a very large archive of previous messages.
2) What is Modula-2?
Modula-2 is a programming language designed by Niklaus Wirth of Pascal fame.
Among other things, it features strong typing,modules, a rich variety of data
types, a powerful set of control statements, procedure types, opaque types,
and coroutines.
3) What about Modula-2 standardization?
There is no standard for the Modula-2 language or library beyond Niklaus
Wirth's classic text, "Programming in Modula-2". There is an ISO committee,
ISO/JTC1/SC22/WG13, which has circulated a number of drafts which have varied
between editions. The current edition is the "2nd Committee Draft Standard:
CD 10514 December 1992." It is distribution has been restricted.
To find out what's happening with standardization, contact the chair of WG13,
Mark Woodman, m.woodman@open.ac.uk.
4) What are Oberon and Oberon-2?
The Oberon language was a part of Wirth's Oberon operating system. Oberon is
the successor to Modula-2 by its original designer,Niklaus Wirth of ETH,
Zurich. In brief, it removes variant records, opaque types, enumerations,
subranges, the CARDINAL type, local modules, automatic qualifications, general
indexing, the FOR and WITH statements, and even the notion of a program or
main module. Oberon adds type extension (inheritance) and, in its purest
form, automatic garbage collection.
Oberon-2 is Oberon with a small set of extensions by H. Moessenboeck, also of
ETH, Zurich. These extensions are type-bound procedures (methods), read-only
export, open array variables, a WITH statement with variants, and the
reintroduction of the FOR loop.
More detailed information can be found in "Software: Practice and Experience"
(July 1988, September 1989) and by anonymous ftp from the host
neptune.inf.ethz.ch:/Oberon/Docu.

Programming_, Vol. 12, No. 4, pp. 179-195, 1991.
5) What about Modula-3, Object Oberon, and Seneca?
Modula-3 is an interesting language designed at DEC Software Research Center,
also as a successor to Modula-2. Unless there is a specific question about
how it relates to Modula-2 or Oberon, posts about Modula-3 would be better
directed to Comp.lang.modula3.
Object Oberon is an Oberon variant designed by H. Moessenboeck and J. Templ
of ETH, Zurich. It eventually evolved into Oberon-2.
Seneca is an Oberon variant focusing on numerical applications and is by R.
Griesemer of ETH, Zurich. It is still under development.
6) Where can I find (preferably free) implementations of Modula-2?
While there have been several implementations of Modula-2, they are not as
numerous nor as easy to find as, for example, C. Some implementations are
listed below. These are merely some commonly used implementations, and should
not be taken as a recommendation of any of the following products. Only
implementors are listed, not distribuors. Free or shareware implementations
receive preferential treatment, as they encourage the new and/or experimental
Modulan.

[ m2c, a Modula-2 to C translator kit ]
From: sgccseh@citecuc.citec.oz.au (Stephen Hocking)
It is in /pub/cocktail/mtc.tar.Z on the machine ftp.karlsruhe.gmd.de,
where the bloke who wrote it all (Josef Grosch) is based. You will also
need reuse.tar.Z and front.tar.Z from the same directory. For those
interested in compilers, that directory is a goldmine. The stuttgart-uni
address was an alternative whose connections were a bit more reliable at
the time.
Ross L Richardson <rlr@postoffice.utas.edu.au> comments:
I believe mtc was originally written by M[atthias] Martin, as some kind
of Diploma project.
Modula-2*
Modula-2* Compiler Available
Modula-2* constructs allow for clear and portable parallel software
without intolerable loss of efficiency. The following list contains
the main advances of Modula-2*:
o The programming model of Modula-2* is a strict superset of data
parallelism. It allows both synchronous and asynchronous parallel
programs.
o Modula-2* is problem-oriented in the sense that the programmer can
choose the degree of parallelism and mix the control mode (SIMD- or
MIMD-like) as needed by the intended algorithm.
o Parallelism may be nested to arbitrary depth.
o Procedures may be called from sequential or parallel contexts and can
themselves generate parallel activity without any restrictions.
o Most Modula-2* programs can be translated into efficient code for both
SIMD and MIMD architectures.
Recently, we put a SPARC/SunOS 4.1.1 binary version of our Modula-2*
compiler "msc" on ftp. This version is now available via anonymous ftp
from iraun1.ira.uka.de:pub/programming/modula2star.
7) Where can I find implementations of Oberon(-2)?
To repeat, this should not be taken as a recommendation of any of the
following products, but. . .
ETH, Zurich has released free implementations of the Oberon system. These
include Oberon compilers. They are available by anonymous ftp at
neptune.inf.ethz.ch:/Oberon/* or gatekeeper.dec.com:/pub/plan/oberon/*.
Oberon-M is an independently produced Oberon compiler for MS-DOS systems that
can also be found at neptune and gatekeeper.
There is also a Modula-2/Oberon-2 to C translator available through
Real Time Associates Ltd.

From: thutt@THAMA1.APGEA.ARMY.MIL
The source to the Oberon compilers is not publicly available however, you
can license the front end and/or the back end for the Oberon-2 compiler
from ETH for 1000 Swiss Francs. The license agreement does prohibits you
from redistributing the source, but you are free to do whatever you want
with any derivative product, provided you give ETH credit for the original
compiler source.
You are also required to make ETH aware of your product, and provide the
product to them should they ask. It does not state if it needs to be
source or executable code, however.
It is a pretty loose agreement, but not so loose to hinder ETH. 1000 SFr
is about 757 dollars, as of last month.

8) Where can I find interesting libraries and sources?
Amiga Sources:
From: htgoebel@cip.informatik.uni-erlangen.de (hartmut Goebel)
At ftp.uni-paderborn.de in /amiga/amok you can get all the disks from the
AMOK series via anonymous ftp. Please download only 18.00 - 8.00 h
(MET), cause the transmitt rate is low. Perhaps someone call move the
disks to overseas, too.
On this series there are several modules both for Oberon and modula2 and
executable programms (most with source). While the Programms almost run
only on the Amiga, the modules may be interesting for other systems, too.
There are modules for many diverent usages, not only generic.
MAS Modula-2 Algebra System
From: kredel@unipas.fmi.uni-passau.de (Heinz Kredel)
MAS is an experimental computer algebra system combining imperative
programming facilities with algebraic specification capabilities for
design and study of algebraic algorithms. MAS views mathematics in the
sense of universal algebra and model theory and is in some parts
influenced by category theory.
MAS (0.3x and 06.x) is available on electronic networks (internet) via
anonymous ftp from: alice.fmi.uni-passau.de = 123.231.10.1
