Modula-2 Frequently Asked Questions Part 2
4. WHERE CAN I GET SOURCE CODE, OTHER INFO?

4.1.1 Is there source or other info available on the net?
A. Here are some net sites I have accessed at one time or another. I
am not sure if all are still available or what is in them.
ftp://ftp.psg.com/pub/modula-2/
http://www.arjay.bc.ca/Modula-2/m2faq.html ( Home of this FAQ)
ftp://ftp.inf.ethz.ch/pub/
ftp://NIC.SWITCH.CH
ftp://ftp.mathematik.uni-ulm.de/pub/soft/modula/

WWW sites
http://dir.yahoo.com/Computers_and_I...ages/Modula_2/

http://i44www.info.uni-karlsruhe.de/~modula

http://modula2.org


4.2 What other FAQs or lists of pages are available?
A1. http://dmoz.org/Computers/Programmin...a-2/Compilers/
A2.http://murray.newcastle.edu.au/users...2/Modula2.html
A3.http://www.unet.univie.ac.at/~a9406973/modula2/

4.3 Where can I find graphics libraries, etc?
A. Try the PMOS library for various platforms at one of the following sites:
ftp://ftp.psg.com/pub/modula-2/code (North America)
ftp://cs.ru.ac.za/pub/languages (South Africa)
ftp://dutiba.twi.tudelft.nl/pub/modula2 (Western Europe)
ftp://ftp.cnit.nsu.ru/pub/msdos/programm.ing/modula2 (Eastern Europe).

4.4 Are there any mathematical libraries available?
A1. See Numerical Procedures in Modula-2 -- authorized translation of
Numerical recipes in Pascal from PolyWare (Klara Vancso):
klarav@telic.nl (work) OR k.vancso@tip.nl (home) The CD-ROM has
the Modula-2 sources. See http://www.nr.com Note that sources given
in this book are of the "quick and dirty" variety and cannot be sold
as such, only in compiled form.

A2. LMathLib is a library that defines a number of mathematical
functions for Modula 2 programs. Unlike other libraries of the same
kind, LMathLib patches the Modula 2 compiler. All library functions
are inlined as assembler code for the Floating Point Unit. This
results in faster code compared to the traditional solution with
subroutine calls. Due to this machine dependent technique, you can
use the library ONLY with the (free) GMD Modula System Mocka for
Linux on INTEL based machines. You can get the LMathLib library via
anonymous ftp from
ftp://tee-1.tee.uni-essen.de/pub/Mocka/(132.252.131.33) Documentation
is included.

A3. MATHPAK 87/32 is available for most 32-bit compilers. A lite
version for Canterbury M2 is freely downloadable from
http://www.webcom.com/mhc/welcome.html

4.5 Where can I get a Modula-2 to C converter?
A: The program mtc is available from
ftp://ftp.ira.uka.de/pub/programming...ail/mtc.tar.gz
ftp://ftp.Uni-Koeln.DE/usenet/comp.a.../modula-2/mtc/
An already ported version for DOS+DJGPP can be found at
ftp://ftp.uni-stuttgart.de/pub/unix/programming/modula/
Several of the compilers available work or can work by producing C or
C++ code and can also serve this purpose. See p1, XDS and Ulm's m2c
(not the same as mtc) listings for examples.


4.6 Where can I get a Modula-2 to Modula-3 converter?
A. m2tom3 is available under the terms of the GNU Library General
Public License from
ftp://ftp-i3.informatik.rwth-aachen....ontrib/m2tom3/
m2tom3 is a system to port Modula-2 programs to Modula-3. It consists
of two parts:
- A conversion program which tries to create a Modula-3 source text
with the same semantics as the Modula-2 input while retaining the
original look and feel as good as possible.
- A base library which tries to emulate the Modula-2 standard library
using the Modula-3 standard library.

4.7 Where can I get a Modula-2 to Component Pascal converter?
A.This is available from http://www.lrz.de/~Bernhard_Treutwein/m2o.txt
Note: Component Pascal is an Oberon dialect, but the translator does
not use any CP specific features, i.e. generates standard Oberon-2.

4.8 Are there any Modula-2 applications around?
A. Besides the items mentioned in 1.11, the Idaho National
Engineering Laboratory (INEL) develops and maintains a now
~350,000 line MODULA-2 reusable component library called SAGE. For
more information on SAGE send E-Mail to hotline@sage.inel.gov or see
the web site at http://sage.inel.gov/homepage.htm


4.9 Are there any compiler construction tools available?
A1. Some old ones appear in ftp://ftp.gmd.de/GMD/cocktail/

A2. Coco/R generates recursive descent parsers and their associated
scanners from attribute grammars. Full source code, and a variety of
simple example applications are supplied in the distribution kits.
The Modula versions (1.50 is the latest) are available from
ftp://ftp.ssw.uni-linz.ac.at/pub/Coco/ and the Java versions are
there too, at ftp://ftp.ssw.uni-linz.ac.at/pub/Coco/javacoco.htm
See also:
ftp://ftp.inf.ethz.ch:/pub/software/Coco
ftp://ftp.psg.com:/pub/modula-2/coco
ftp://cs.ru.ac.za:/pub/coco
ftp://ftp.fit.qut.edu.au:/pub/coco
There are versions for the MS-DOS compilers (JPI, FST, Logitech,
StonyBrook, Gardens Point), for the Mocka compiler for Linux and
FreeBSD, as well as for the Gardens Point Unix compilers, including
Linux and FreeBSD. There is also a version that produces TurboPascal
units very similar to the Modula-2 modules. This is also FreePascal
compliant now. A port for the p1 compiler on Mac OS 9 is also
available. Latest information is available at
http://cs.ru.ac.za/homes/cspt/cocor.htm. Pat Terry's textbook
"Compilers and Compiler Generators" that uses Coco/R is now online at
http://www.scifac.ru.ac.za/compilers

A2. A copy of the EBNF for ISO Modula-2 can be found in Appendix 3 of
the shareware text at:
http://www.modula-2.com

4.10 Is there an applications framework for Windows programming?
A. Try looking at
ftp://ftp.ifi.uio.no/pub/sjr/m2afx.zip
orftp://ftp.leo.org/pub/comp/platforms/pc/windows/programming/modula/m2afx.zip

This software is an application framework that implements a number of
classes that encapsulate the weirdness of the Windows C API and
attempts to present it in a cleaner way to the Modula-2 programmer.

4.11 Does there exist something to convert a C header file to a
Modula-2 DEFINITION MODULE file for me?
A. Try looking at the XDS Ltd site for the H2D freeware product on
some platforms

4.12 Where can I get the C code of a Modula-2 compiler?

A. Most Modula-2 compilers are written in Modula-2. It seems
rather strange to me that one would want to trust the compilation of a
good language to a tool written in a poor one.




4.13 What can I do with* old sources from Modula Corp?

A. From the former president Richard Ohran (ROhran@vinca.com):
"Modula Corp. is dead. Do whatever you like."



4.14 Are there source code examples anywhere for Windows programmers?

A. Translations of Example Programs in Charles Petzold's book
"Programming Windows 95" from Visual C++ to Stony Brook and XDS
Modula-2 by Peter Stadler, Vienna can be found at:
http://www.nhm-wien.ac.at/Petzold/Index.html


4.15 Isn't there a Modula-Prolog project somewhere?

A. Try ABB Corporate Research and Carlo Muller, who may license it to
you for non-commercial purposes. mailto:cadamuller@swissonline.ch

4.16 Is C. Lins SCL library available?

A. Yes, at

http://www.aha.ru/~uranus/download/scl.zip

4.17 Can you help me with my assignments?
A1. Some people may give you hints, but please do not subvert your
professor and your education by submitting work other people do for
you.

A2. Here are two answers submitted to the newsgroup in response to a
desperate student's plea for ANY Modula-2 program. The first is
rather prosaic; the second a little more imaginative:
MODULE homework;

IMPORT STextIO;

BEGIN
LOOP
STextIO.WriteString ("I will do my own homework.");
STextIO.WriteLn;
END;
END homework.

main()
{
int i;

for(i=0; i
