What is new in version 2.31 (2005 09 09)?
Well, the keeper of the FAQ got more mail in the three days after posting 2.30 than in the previous entire year. As a result, here's a new edition. This one has another revision of A8 under 1.11, a new use under A9 of the same section, and a revised comment on GM-M2 in A4 of that section. I have also revised answers relating to the Mac to clarify that older compilers support only Classic, not OS X. Also, in the last few days, the BURKS project at Brighton has become defunct, so all references to this resource have been removed.
What was new in version 2.30 (2005 09 03)?
It has been nearly a year since our last edition, and most changes are minor. However, some new activity is worth mentioning, most noteably the GNU Modula-2 project (which we have promoted to its own question at 1.16), and the Objective Modula-2 project for Cocoa which has its own mention at 1.17. In addition, we note a change to the Gardens Point web address, a new freeware release for Amiga emulators by Tom Breeden called Aglet Modula-2, a new question on syntactic sugar at 5.14, and new observations by the keeper of the FAQ at A8 (renumbered) in the section on uses of Modula-2. Some errors in the html have also been corrected.
SUMMARY:
1. Answers to many questions about Modula-2 as a programming notation may be found in the shareware textbook. As always, users should pay the shareware fee. See section 1.4.
2. Answers to most other frequently asked questions about Modula-2 will be collected by Rick Sutcliffe at Trinity Western University and included in this document from time to time as it is revised.
3. Submissions should be mailed to -- rsutc-AT-arjay.bc.ca (modify address in the obvious way)
Anyone making a submission guarantees that they have the right to do so (copyright holder, or information in the public domain.) and that the information is not from any source whose copyright lies with another.
4. I will update this summary file and post to the newsgroups comp.lang.modula2 and to comp.answers and news.answers
5. The latest version will always be available in a Nisus (Mac) form in

Appendix: AUTHOR INFORMATION AND DISCLAIMERS
\1. WHAT IS MODULA-2?
A. Modula-2 is a programming notation that corrects some of the deficiencies of Pascal. It is suitable for learning programming, for large projects written and maintained in the fashion of professional software engineers, and for real time embedded systems. Modula-2 is small, expressive, easy to learn, and to read.
1.1 Who developed Modula-2?
A. Modula-2 was developed by Niklaus Wirth at ETH in Zurich, Switzerland in the late 70's. Wirth also developed Algol-W, Pascal, Modula, and Oberon and the Lilith computer, a natively Modula-2 machine (see section 1.15).
1.2 Where is this language described?
A. In Programming in Modula-2 3rd edition published by Springer-Verlag in 1985. For the purposes of distinguishing this from later variants, this description will be referred to herein as classical Modula-2.
1.3 How do you pronounce Herr Wirth's name?
A. It is incorrect to call him by his value (worth.) Instead his name is veart.
1.4 Can I get a simple introduction to ISO Modula-2?
Yes, the latest revised and corrected edition of the shareware text as of 2004 is at http://www.arjay.bc.ca
Mirror (for the text, not the FAQ):
1. TWU http://www.csc.twu.ca/rsbook/index.html
1.5 How does Modula-2 fit into the language zoo?
A. It is a descendent of Pascal and Modula, and one predecessor of Modula-2+, Modula-2*, Modula-3, Oberon, Oberon-2, and various object oriented versions of these. The latter languages are not replacements for Modula-2, merely later notations in the same family, having strengths and weaknesses of their own. Modula-2 is sometimes classified with Ada and C as the trio of modern languages in view of their expressive power. Modula-2 is smaller and more readable than either.
1.6 What are the differences between Modula-2 and Standard Pascal?
A. Modula-2 has separately compiled library modules, and makes much less use of blocks (begin...) than Standard Pascal. Identifiers are case sensitive; there is no goto label; and I/O is in libraries rather than built in. The IF statement is more versatile; and there are facilities for concurrent programming via coroutines. Extended Pascals may have some of these features.
1.7 What is ISO Standard Modula-2?
A. A committee of ISO JTC1/SC22/WG13 with delegates from several countries met after 1987 to work on a standard description of Modula-2 and a set of standard library modules.
A2. The official home of the ISO Modula-2 working group WG13 is at http://sc22wg13.twi.tudelft.nl/
1.7.1 What is the status of ISO Standard Modula-2?
A. The international standard (IS 10514) was voted on and is official. The Object oriented extensions and Generic extensions were also voted on and are official.
1.7.2 Where can I get the Modula-2 standard?
A1. Contact your national standards body or ISO (the publisher.)
A2. For a slightly older version, try looking in ftp://ftp.mathematik.uni-ulm.de/pub/soft/modula/standard/draft4/
1.7.3 What format is the standard document in?
A. Latex.
1.7.4 Who was the convenor of the standards group (WG13)?
A. Martin Schoenhacker of Vienna was the last convenor.
1.7.5 When was the last WG13 meeting?
A1. It was March 17-18 1997 in Linz, Austria. For more details, follow http://sc22wg13.twi.tudelft.nl/docs/meetings.html
1.7.6 When is the next WG13 meeting?
A1. No meeting is currently on the schedule. One may be held if necessary to do routine maintenance on the standards, but at this time WG13 is in maintenance mode--not operating actively.
1.7.7 Will I be able to read the standard?
A1. The concrete syntax is written in a variation of EBNF (Extended Backus-Naur Formalism) and should be accessible to most.
A2. Much of the base document's details are written in VDM-SL (Vienna Development Method - Specification Language) which is a formalism for giving a precise definition of a programming language in a denotational style. It is worth learning VDM-SL if you plan to write a compiler or use formal methods to do any design work.
1.7.8 Can I at least get electronic copies of the definition modules?
A. Yes, in ftp://FTP.twu.ca/pub/modula2/ISOLibraries/ISODEFMods/ or ftp://ftp.mathematik.uni-ulm.de/pub/soft/modula/standard/libdefs/
1.7.9 Can I get ISO library code to port?
A. Yes, a partial ISO library is available from Rick Sutcliffe, the FAQ maintainer. He has done an ISO I/O library for the Mac, and StonyBrook ported this to their system. Anyone else is welcome to do a port provided: (1) TWU gets a license to the software produced (2) All code changes are marked and submitted to Rick Sutcliffe for the benefit of anyone else who wants to do a port.
1.7.10 Can I get copies of the grammer?
A1. Yes, in http://www.twu.ca/rsbook/Appendices/Ap3.html
A2. For classical Modula-2, see also Coco (section 4.9)
A3. There are nice syntax diagrams for classical Modula-2 in http://cuiwww.unige.ch/db-research/Enseignement/analyseinfo/Modula2/BNFindex.html
and there are syntax diagrams for ISO Modula-2 stored at http://www.twu.ca/rsbook/Appendices/Ap2.html
1.8 What difference is there between classical and ISO Modula-2?
A. ISO Modula-2 has resolved most of the ambiguities in classical Modula-2. It adds the data type COMPLEX and LONGCOMPLEX, exceptions, module termination (FINALLY clause) and a complete standard I/O library. There are numerous minor differences and clarifications.
1.8.1 What else has WG13 done?
A. WG13 has completed two additional standards (separate from the main one) for (a) object oriented Modula-2 and (b) generic programming facilities. Older versions of the generics proposal are stored in the directory ftp://FTP.twu.ca/pub/modula2/WG13/
1.9 What is (was) Turbo Modula-2
A. Borland prepared CP/M versions of Modula-2 and sold them for a time in Europe (also in North America via a distributer.) One of these versions later migrated to become TopSpeed Modula-2.
1.10 What is (was) Top Speed Modula-2
See also 1.9. Eventually, Top Speed merged with Clarion, a maker of database products, who used Modula-2 as their DB language, and for a time sold Top Speed separately. Later still, this became SoftVelocity, but the Modula-2 compiler has vanished. A fuller history is available at http://www.attryde.com/clarion/.
1.11 Where and for what is Modula-2 used?
A1. Modula-2 is widely used for teaching the fundamentals of sound programming techniques, data structures, and software engineering in many parts of the world. It has been the language of choice in much of Europe, though Java and C++ have made great inroads. Modula-2 has features that make it superior to other languages for large projects and for programming and real time controllers.
A2.Here is a reply by Andrew Trevorrow (akt@kagi.com) who is the author of the Macintosh programs written in p1 Modula-2: OzTex (standard Tex implementation on the Mac) X-Words (a meta-Scrabble word game), Anagrams (a fast and friendly anagram generator), LifeLab (a software laboratory for 2D cellular automata.) His home page is: http://www.trevorrow.com/
"Back in 92-93 I worked for the Australian National Uni's Research School of Earth Sciences writing Noble, a large suite of programs to control mass spectrometers and analyze all the data. Everything was written in Modula-2 (the only reason I took the job!). In fact, one of the reasons I decided to try making a living from shareware was so that I could keep using Modula-2."
A3. General Motors and its subsidiary Delco have done their programming in General Motors Modula-2. Up to a point, all GM car computers were programmed in this language, though the keeper of the FAQ is unable to confirm that this is still the case.
A4. Here is a message sent in by a maker of test equipment:
Our BoardWizard range of test equipment has compilers,pseudo-code interpreters and a complete test operating system written in M2. The code was written for one tester in 1987 and has been maintained from that date to the present. New tester models have added and new interface and UI code has been written, indeed sections have been completely re-written but much of the core test logic is untouched since about 1990 when I shifted to management. Much of the code is unknown to those who maintain it - yet when i look at it after several years I can still explain it to others even though comments are sparse. I believe that that is the hallmark of a great programming language. (Emphasis added.)

A5. Here is an answer sent in by a developer:
Magic Mouse Productions 12615 Sir Francis Drake Blvd. Inverness, CA 94937 USA 1-415-669-7010 http://www.magicmouse.com
The following products were made using Modula-2. The programs are all about 100,000 lines long, and 99% Modula-2, with about 1% assembler code for performance in critical areas.
Flying Colors 2, Anime Designer DragonBall, Action Designer Ultraman, Tamagotchi
Sketch, Curious George Paint and Print Set -- all paint and creativity programs.
Gorgeous Mail -- a new years card making program
JuniorNet web activities -- various creativity activities for JuniorNet web subscription service
Discus -- CD label making program
Web Workshop Deluxe -- Web site design product
A5A. Here is a later rant sent in by the same person.
We make commercial software using Modula-2, and have been doing so since the first appearance of the Logitech "Multiscope" compiler about 17 years ago, and about a million lines later we are still using Modula-2 to great effect.
I am proud to announce that Web Workshop Pro, a kids website editor, is about to go "golden" and be released to the public. The program, written in 98% Modula-2 (with a small assembler section), is reliable, fast, and very efficiently coded. An almost identical product in feature set and user interface style (but not as good) called Site Central was written in C, and is 4 times larger in executable. There is no better way to compare languages than to see two similar products implemented in the same environment (macintosh + windows), and see the result.
We use the excellent StonyBrook compiler (a fully integrated development environment) for Windows, and the wonderful p1 compiler under the Macintosh MPW development environment (ed. note: Classic only).
We have a porting tool which converts between the two compilers, although recent improvements to the StonyBrook compiler make it almost possible to have identical source code.
We have implemented a quickdraw emulation layer for windows which allows programs to run identically between macintosh and windows platforms. This very layer eluded a very large company years ago, and is crucial to having a single code base that operates on the mac and windows in an identical manner.
100,000 lines of code, about 10 months to do. one programmer. Less than 100 total bugs. I have an 800kb demo if anybody wants to have one e-mailed.
Until I get a chance to build a compiler for my BEADS language, which will reduce programming effort by at least 10:1, Modula-2 is the simplest, cleanest, easiest to read, tends-to-build-a-reliable-product language on the planet.
Java stinks! Modula-2 rules! (editor's note: Ouch!)
A6. Frank Schoonjans mention MedCalc (statistical software for Windows, http://www.medcalc.be, developed using Stony Brook Modula-2, his main work.

A8. (revised 2005 09 06) The keeper of the FAQ notes that he still occasionally gets contracts to evaluate Modula-2 code in takeover situations and the like. Usually this code is for controllers, other real time devices, telecommunications applications, and the like (sorry, specifics are under non-disclosure). However, there can be little doubt that apart from real time applications, Modula-2 use has declined steadily since the early 1990s. The author still finds it invaluable for teaching new programmers good habits, but acknowledges that without a new suite of uses, little will remain of it in a few more years. Perhaps the GNU project and the Objective Modula-2 project for Cocoa (and other environments already using Objective C) will breathe new life into the language. Modula-2 is not the only good notation to suffer in the mad rush to conform to C++ peer pressure. Overweight big brother Ada has also vanished. Lots of real-life programmers use Delphi (Pascal++) but there are virtually no textbooks available. Likewise for Smalltalk.
A9. The Proceedings of the Joint Modular Languages Conference, JMLC 2003 (LNCS 2789), contains an article by Koltashev wherein he discusses the benefits of using Modula-2 for the onboard-software used in Russian telecommunications satellites.
1.12 Why do some universities use Modula-2 for teaching instead of C or C++?
A1. Modula-2 is a type-safe language and its compilers will therefore catch many errors that otherwise show up only at run time. While professional programmers need to learn C++ because it is commonly used, it is important to begin a discipline of deliberate, engineered programming at the outset. Modula-2 is easier to write in, easier to read (it reads left to right) and easier to debug. It lends itself well to software engineering of very large projects. Modula-2 is a higher level language than C++, particularly with respect to pointers, all of which have types that depend on what is pointed to, and that can be treated as addresses only by flagging this fact in the code. A good computing science department (such as the one at Trinity Western University, where I teach,) tries to inculcate a way of thinking (as a software engineer, not a hacker) and beyond that, a breadth of ideas. At TWU C, C++, Java, Prolog, php, and other languages, are taught in appropriate courses, and on a variety of platforms, but not to beginners. Frankly, if I had to switch, my first choice would be Delphi, Ada or Oberon, and after that Java (if it ever became reliably cross platform.) If I had to try teaching beginners C++, I would retire. Objective Modula-2 seems interesting, though.
A2. Popularity no more implies soundness or superiority when considering tools such as Modula-2 and C++ than it does when considering hardware (Pentium vs PowerPC), operating systems (Windows vs Mac) and applications (Word vs Nisus). Marketing means selling the sizzle of appearance not the steak of content; those who know this and can apply it consistently win the marketing wars with inferior or even poor products. The market situation is no reason to give up on the basics of sound tools and methodology. If anything the cirisis implied by the inability of large companies to maintain poorly designed and bloated software and OSs implies that the industry needs to return to basics before it is going to advance much farther.
1.13 Why is Modula-2 a good language for large commercial projects?
A1. It supports modular design which reduces errors and cuts down on maintenance time. This also allows platform dependencies to be isolated, increasing portability. I/O is found in several type-specific modules, so linkers only patch in the I/O code that's needed, making programs smaller and faster. This is in sharp contrast to, say, the versatile but resource hungry printf in C.
A2. see: Griffith, Laurie Modula-2 is three times less error prone than C, Proceedings of the Second International Modula-2 Conference, Loughborough University of Technology, UK, September 1991, pp 332-338.
1.14 Where do I get information on YAFL?
A. This is yet another OO and Generic derivative of Modula-2. The homepage for the language is at http://www.phidani.be/yafl/index.html
1.15 Where do I get information on the Lilith Computer?
A. This was the natively Modula-2 machine Wirth once built. A collection of documentation and other material is located at http://cfbsoftware.com/modula2/
1.16 Is there a GNU Modula-2?
There is a GNU Modula-2 project which is alive and well and its web site is: http://floppsie.comp.glam.ac.uk/Glamorgan/gaius/web/GNUModula2.html and it can also be found from GCC web site: http://gcc.gnu.org/frontends.html. The current release status of GNU Modula-2 is 0.49 and it implements the PIM variant of Modula-2. It provides a set of PIM libraries and also installs the ULM PIM libraries. It is sufficiently stable to build on Sparc Solaris in 64 bits and also GNU/Linux on Opteron/Athlon in 64 bits. It also builds on BSD and GNU/Linux on the x86 in 32 bits. Its aim is to be both ISO and PIM Modula-2 compliant. (Also, see the next question).
1.17 Are there any M2 compilers that support Cocoa and/or GNUstep, say an Objective Modula-2?
A: At present there is no M2 compiler which supports Cocoa or GNUstep. However, a project is under way (as of 2005 07) to define language extensions to support the Objective-C object model and interface with the Objective-C runtime, which is necessary in order to develop applications for Cocoa and GNUstep. The idea is to add extensions in support of OO to a base Modula-2 which are equivalent to the extensions by which Objective-C was created as a superset of C, but do so in a way that is in line with Modula-2 style syntax. It is intended to support those extensions in GNU Modula-2.
2. WHERE IS MODULA-2 DISCUSSED?
2.1 COMP.LANG.MODULA-2
This is an internet newsgroup for questions, answers, and discussions on Modula-2. You may read it under this name on any machine on which you have a news account.
2.1.1 How do I post a message to comp.lang.modula2?
A. Post it directly into that group using a news program on any computer connected to the network. Alternately, you can surf to the forums at Arjay Enterprises, sign up as a member, and there read and post to the newsgroup via the forum. Use the URL http://arjaybb.com/viewforum.php?f=15.
2.1.2 How do I retrieve old messages from comp.lang.modula2?
A. Your local news server probably keeps old messages only for a few weeks. You should be able to mark the entire group as unread and browse whatever is available there. The last couple of years' are on the forum at arjaybb.com.

3.4 Is there such a thing as a decompiler for Modula-2?
Nope. But feel free to write one. Be sure to include a facility to produce the planning documents from which the Modula-2 code could be constructed and one to find out what the users wanted before the planning documents were written.
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)

http://cs.ru.ac.za/homes/cspt/modula2.htm
4.2 What other FAQs or lists of pages are available?
A1. http://dmoz.org/Computers/Programming/Languages/Modula-2/Compilers/
A2.http://murray.newcastle.edu.au/users/staff/peter/m2/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.comNote 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
Features: Written fully in INTEL CPU machine language Math Coprocessor control Basic Math functions Vector and Vector-Scalar Routines Vector and Vector-Scalar 'Skip' Procedures Complex Number Routines Complex Vector and Vector-Scalar Routines Polynomial Manipulation Routines Simple Matrix and Vector-Matrix Routines Solving Systems of Linear and Nonlinear Equations Unconstrained Minimization Nonlinear Least-Squares Minimization Eigenvalues and Eigenvectors Singular Value Decomposition Extrapolation of Vector-Sequences Statistical and Data-Fitting Rountines Fourier Transforms and Convolution Spectral Analysis Routines Numerical Integration Differential Equations
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/cocktail/mtc.tar.gz
ftp://ftp.Uni-Koeln.DE/usenet/comp.archives/languages/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.de/pub/Modula-3-Contrib/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. contact: Peter Klein office: Ahornstrasse 55, 52074 Aachen, Germany e-mail: pk@i3.informatik.rwth-aachen.de. Tel.: +49/241/80-21316 Fax.: +49/241/8888-218
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. 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

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:
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 i++)
printf("I will do my own homework.\n");
}
Followup Question: Is that Modula-2? I just finished my first course in Modula-2 and that don't look at all familiar. I'm not looking forward to the final exam.
A. (Pat Terry) Computer Science changes sooo rapidly. Haven't you discovered Modula-2++ yet?
5. SPECIFIC QUESTIONS ON CODE AND ALGORITHMS
5.0 Where can I get general information on algorithms?
A Try the site http://www.cs.sunysb.edu/~algorith/
5.1 Where can I get an algorithm for an efficient random number generator?
A1. Pierre L'Ecuyer: Efficient and Portable Combined Random Number Generators, Communications of the ACM, vol. 31, no. 6, pp. 742-749. The RNG has a period of approximately 2.3E+18. Generating 1 000 000 numbers per second, that means that it would take over 73 000 years before it repeated a sequence.
A2.Look in the PMOS library. This one uses the 'Minimal standard random number generator' described by Park & Miller, CACM 31,10,Oct 88 p1192. The code has been checked for the 10001st random as specified in Park & Miller p1195. One site is: ftp://ftp.psg.com/pub/modula-2/code/random/
A3. A pseudo random generator using the subtractive method taken from Knuth, Seminumerical Algorithms, 3.2.2 and 3.6, belongs to Ulm's Modula-2 System that is distributed under the terms of the GPL (and in case of the library under the terms of the LGPL). More informations may be found at http://www.mathematik.uni-ulm.de/modula/ and http://www.mathematik.uni-ulm.de/modula/man/man3/RandomGenerator.html
5.2 How can I prevent NIL pointer errors?
A.First guard your reference by writing
IF (myPointer # NIL) AND (myPointer^.fieldname =)...etc.
Because Modula-2 has short circuited Boolean expression evaluation, the first part guards the second from being evaluated inappropriately. Then, take the radical, unC-like step of checking your code design for the logical error that led to the incorrect reference in the first place.
5.3 Why doesn't my IF statement compile?
A.See the example in the last subsection. Boolean expressions must be delineated with parentheses.
5.4 Can I assume numeric variables are set to zero and Booleans to FALSE?
A. No. The values of variables are random until your code sets them. Declaring does not initialize.
5.5 Why do conversions from real to whole types sometimes crash?
A.You need to protect your conversion code by using MAX (TYPE) and MIN (TYPE) which are part of the ISO Modula-2 base language.
5.6 Does a CASE statement always need an ELSE clause?
A. No, but it's not a bad idea, even if you think you have covered all the cases. If you have, a good compiler might optimize your code away, but if you haven't, you could be in for trouble.
5.7 What are the system types to which all other parameters are compatible?
A.Just LOC and ARRAY OF LOC (one dimension). This does not work for multidimensional arrays of LOC, and there are no defined BYTE and WORD types, though implementations may include them as well.
5.8 How do I control the serial port, mouse, network card, TCP/IP or other communications protocol or peripheral?
A.These are system dependent, and no modules for this can be found in the standard. A vendor MAY supply them. Ask.
5.9 Does the object model for OO-Modula-2 have garbage collection or not?
A. BOTH traced (collected) and untraced (roll your own memory management) objects are available in ISO OO Modula-2.
5.10 What is the arity of inheritance for OO-Modula-2?
A. Single inheritance only.
5.11 What do you use the generic extensions for?
A. These allow you to write code for structures such as lists or queues, or for routines such as a sort, without initially specifying the data types that are in the structure or the target of the routine. The initial module is called a generic module. Such modules can be refined for the specific data types by a refining separate module (library) or a refining local module.
5.12 How do I clear the screen?
A. This non-standard functionality may be present in a module called Terminal.
5.13 How do redirect screen and keyboard I/O?
A. This non-standard functionality may be present in a module called InOut or (in an extension to ISO versions) in RedirStdIO. The procedure to use is OpenInput (or OpenOutput). Unfortunately these behave differently in every version (one of the reasons we built a standard). Some versions produce a prompt at runtime, others take a file name. The latter may or may not require a file extension. They may look for the name as you have provided it and if they don't find it, try with the default extension .txt Others have a way of entering the extension. You will have to consult the documentation.
5.14 Why use the colon before the type in a VAR declaration, and why have the vertical bar as a case separator rather than a semicolon?
A. The se are both "syntactic sugar" to help the compiler know what it's doing. For instance, if there were no colon in a type declaration, the compiler would not know the last identifier is supposed to be a type name because it wouldn't know it was last until checking the next token. Lookaheads are expensive. Also, there was no need for subsequent committees and designers to change this from Wirth's definition. After all, there is no ambiguity here.
6. WHAT ARE SOME REFERENCE MATERIALS ON MODULA-2?
A1. A shareware text I have written (and that MAY be the only currently maintained English language instructional text on Modula-2) is available. See section 1.4.
A2.The manuals for some of the commercial products contain much useful information.
A3. The Gardens Point sites have documentation available (see their listing above.)
A4. A document called Modula-2 for Pascal programmers (Postscript,10 pages) may be fetched by anonymous ftp at ftp://ee.newcastle.edu.au/pub/modula2/Modula2.ps.Z
The author has not updated the contents for a couple of years, so there may be inaccuracies in terms of the current language standard.
A5. A variety of ETH papers are stored at ftp.ftp.ethz.ch in /doc/diss, /doc/tech-reports and /pub/oberon/docu

7. REVIEWS OF MODULA-2 PRODUCTS.
Note: The reviews have been contributed by others and I take no responsibility for their accuracy or for any opinions expressed therein. I have updated some of the facts.
p1 Modula-2 v5.2 for Macintosh Classic (pre- OS X), by Marc Martin, Dec 1994.This is an excellent Modula-2 compiler, implemented as an MPW Tool. Highlights include ISO language extensions & library, a full set of Macintosh toolbox definitions, language extensions to simplify toolbox programming, object-oriented extensions and support for MacApp, greater than 32k code and globals, code generation comparable to Apple's official compilers, several FPU code options, multi-window debugger, linkable with other MPW languages, detailed documentation, and superb technical support via e-mail. Downsides include high cost (US$400), dependency on MPW, lack of SADE support. Version 6.0 has been released for creating PowerPC programs under MPW or CodeWarrier (The latter now defunct).
Appendix: AUTHOR INFORMATION AND DISCLAIMERS
Personal: I have used, written about, and taught Modula-2 (since 1983) and have maintained some of the information in this list for many years. I have used at least a dozen different compiler/environments in that time on five different platforms, and have written numerous articles and reviews for publication. I have been a member of the ISO committee WG13 (Modula-2 standardization) since its inception and have participated in all the debates and meetings of WG13 except for meeting #9 at Lake Wanaka, NZ. I have written a text on Modula-2 (now shareware), made numerous submissions to WG13 and directed an implementation of the ISO I/O library in order to verify its concepts. I am the author and project editor of Standard Generic Modula-2, and am involved in the effort to create Objective Modula-2.
Disclaimers:
(i) I take no responsibility for anyone's use or misuse of this information.
(ii) Apart from having been a beta tester, textbook writer, programmer and a long time user of Modula-2, I have no financial connection with any manufacturer or distributor of software. I am the author of some Modula-2 materials (some of which are shareware) as noted herein, and of various other books. Some manufacturers may distribute my shareware on CD-ROM for a previously arranged fee, but that is not an endorsement of their products by me or of mine by them.
(iii) In producing this material, I am NOT acting in an official capacity for TWU, WG13, ABC, IEEE, ACM, comp.lang.modula2, the GNU or Objective Modula-2 efforts, or any other organization.
(iv) Mention of a book or product is NOT an endorsement unless specifically noted.
(v) Inclusion of materials on this list is based on relevance to Modula-2 and factual content and is otherwise entirely without prejudice. I reserve the right to edit all submissions for brevity, clarity, and usage.
