                 Modula-2 Frequently Asked Questions

What is new in version 2.16?There are more chapters in the Modula-2
shareware book and errors in chapters 8, 9, and 16 have been fixed. See
section 1.4.

Situated in the same location, and accessible from the book index or from
http://www.twu.ca/rsbook/Builder/copyright.html are some chapters of a
novel I have written. Your feedback is invited. It has nothing to do with
Modula-2, however.
Section 4.9 has been cleaned up and includes mention of the new CocoCOCO
versions for Java. The broken Modulaware link is fixed.

What was new in version 2.15?
The Mandeno Granville listings have been updated. The COCO listings have
been revised to reflect the availability of the Mac version. Some out of
date material has been removed. XTech is now just XDS. Modulaware has a new
Web and e-mail address. I have created a new answer at 2.7 in the
discussions area for Guenter Dotzel's ModulaTor publication.


=====================================================
SUMMARY:
1. Answers to many questions about Modula-2 as a programming notation may
be found in the shareware textbook. See section 1.41.4.
2. Answers to most other frequently asked questions about Modula-2 will be
collected at Trinity Western University and included in this document from
time to time as it is revised.

3. Submissions should be mailed to -- [e-mail]
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
ftp://FTP.twu.ca/pub/modula2/m2faq.html
The folder modula2 has a variety of other materials. This version of the
FAQ is readable as text by other word processors, but without any
formatting. It is also available from the site rtfm.mit.edu in plain text
form as

=====================================================
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.


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 Pascal and Oberon.


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 edition of the shareware text as of 1997 07 23 is
at http://www.twu.ca/rsbook/index.html
Mirrors:
1. TWU CS Students (Internal only) http://www.csc.twu.ca/rsbook/index.html
2. Brighton, UK  http://www.comp.it.bton.ac.uk/rsbook/index.html
3. Vienna, Austria  http://eiunix.tuwien.ac.at/Modula-2/rsbook/index.html
4. the U.S. http://www.mesastate.edu/~ethomson/modula2/

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 Pascal?
A. Modula-2 has separately compiled library modules, and makes much less
use of blocks (begin...) than 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.


1.7 What is ISO Standard Modula-2?
A. A committee of ISO JTC1/SC22/WG13 with delegates from several countries
has met since 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) has been voted on and is now official.

1.7.2 Where can I get the Modula-2 standard?
A1. Contact your national standards body or ISO (the publisher.)

A2. For an 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 is the convenor of the standards group (WG13)?
A.Martin Schoenhacker of Vienna is the convenor.

1.7.5 When was the last WG13 meeting?
A1. It was March17-18 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 respond to comments on Generics and OO proposals.

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 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, this is available from Rick Sutcliffe, the FAQ maintainer. He has
done an ISO I/O library for the Mac, and StonyBrook has 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.htmlA2. 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.htm
l
 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 is WG13 doing?
A. WG13 is working on two additional standards (separate from the main one)
for (a) object oriented Modula-2 and (b) generic programming facilities.
Both passed the registration ballot as CDs and will proceed to final
drafting 1997 05 01. Various versions of the latest generics proposal and
the disposition of comments 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 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 is the language of choice in much of Europe. It 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 ([e-mail]) 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.kagi.com/authors/akt/

 "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 do their programming in General
Motors Modula-2.

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.)

1.11 Why do 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 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 in. It lends itself well to software engineering. 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 which can be
treated as addresses only by flagging this fact in the program code.

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). 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.

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 Oberon and Modula-3?
A. These languages have their own newsgroups. The Modula-3 FAQ is located
at http://www.vlsi.polymtl.ca/m3/ and Oberon has an interesting page at
http://www.math.tau.ac.il/~laden/Ob-pkgs.html

1.15 Where do I get information on Modula-2*?
A. Try http://wwwipd.ira.uka.de/Tichy/m2star

1.16 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
