=====================================================

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.
see: http://www.stfx.ca/people/jandrea/m2/nwirth/


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, at http://www.twu.ca/faculty/fnas/math/rsbook/Welcome.html
Mirrors: http://eiunix.tuwien.ac.at/Modula-2/rsbook/


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 will be
official as soon as the comments have been attended to.


1.7.2 Where can I get the Modula-2 standard?
A1. Contact your national standards body or the IEEE.

A2. 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. Kees Pronk c.pronk@twi.tudelft.nl has been appointed by SC22 as interim
convenor of WG13. It is expected that a new convenor will be appointed
soon.


1.7.5 When is the next WG13 meeting?
A1. It will be June 3 in Oxford, UK.  For more details, follow
http://sc22wg13.twi.tudelft.nl/docs/meetings.html



1.7.6 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 take
a course in formal methods.


1.7.6 Can I at least get electronic copies of the definition modules?
A. Yes, in ftp://FTP.twu.ca/FTP/pub/modula2/ISOLibraries/ISODEFMods/ or
ftp://ftp.mathematik.uni-ulm.de/pub/soft/modula/standard/libdefs/


1.7.7 Can I get copies of the grammer?
A1. Yes, in
http://www.twu.ca/faculty/fnas/math/rsbook/Appendices/Ap3.nisus.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
.htmlhttp://cuiwww.unige.ch/db-research/Enseignement/analyseinfo/Modula2/BNF
index.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. A
ballot is at least several months away. Various versions of the latest
generics proposal are stored in the directory
ftp://FTP.twu.ca/FTP/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 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.)

1.12 Why do universities use Modula-2 for teaching instead of C or C++?
A. 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.
A2. Here are the results of a survey of university usage of Modula-2 done

1.13 Why is Modula-2 a good language for large commercial projects?
A1. It supports modular design which reduced 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/faq.html 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

You should be able to mark the entire group as unread and browse whatever
is available there.

2.2 INFO-M2 (more or less dead)
This is a remailer or mailing list on Modula-2 topics. It used to be
connected to comp.lang.modula2 and share a common message base, but it is
no longer, and has become somewhat dormant. You may receive the messages
that go to this list by sending the following message:
to: listproc@list.cren.net

subscribe info-M2 Nellie Hacke r use your first/last names
HELP this is an optional command for info on these mail lists
Save the message that you get back from the list server.


2.2.1 How do I post a message to info-m2?
A. Mail it to info-m2@list.cren.net Do not however, mail your listserv
commands to this address or everybody will get them


2.2.2 Send a message to listproc@list.cren.net as above, with the command
index info-m2 in the body. You can then send a get info-m2 logxxxx command
for specific message(s), or a help command to learn how to use the
listserv.


2.3 Compuserve
If you have a Compuserve account, GO CODEPORT to join the portable
programming forum.


2.4 Amiga lists
2.4.1 A general list for Amiga Modula2/Oberon programming.  This is
available in a similar manner at amiga-m2@virginia.edu. It is not oriented
toward any specific compiler.Mail to cbt-general-request@virginia.edu to
subscribe.


2.4.2 A mailing-list for the Amiga Turbo Modula-2 Compiler written by
Amritpal S. Mann. To subscribe, send a message to
maillist@econet.demon.co.uk with SignOn turbo-list as the Subject. Once
subscribed, you will receive a copy of all messages sent to the address
turbo-list@econet.demon.co.uk.


2.5 Gardens Point Modula-2
To join the GPM mailing list, send mail to majordomo@dstc.qut.edu.au with
the subject line blank and the body
 of the message containing:
  subscribe gpm
  info gpm
  end
Mail sent to gpm@dstc.qut.edu.au gets automatically forwarded to all
 subscribers on the list. The development team are of course subscribers.
