                Modula-2 Frequently Asked Questions

What is new in version 2.28(2003 10 10)?
A couple of new websites have sprung up and are indicated in section
4.1 and 4.2 One of the sites previously mentioned in 4.9 is gone, so
the answers have been renumbered. What was in section 4.10 has
vanished behind a firewayy (or into the bit bucket) so the rest of
that section has been renumbered. Traffic to the Modula-2.com site is
up again, and so is interest in universities printing the shareware
text. The GNU Modula-2 version seems to be alive, and their web link
has been alered slightly.

What was new in version 2.27(2003 03 26)?
Very little to be honest. The traffic to Modula-2.com has declined dramatically and few people seem to be reading the FAQ except for a
handful of students. A new answer, A6 has been added in 1.11. An
invalid Gardens Point URL has been changed. PMI has been removed. The StonyBrook Section has been revised with new information. We'll prune
the dead stuff again in June, and no doubt make it a lot shorter.



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@arjay.bc.ca
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 http://www.arjay.bc.ca/Modula-2/m2faq.html.
It should also be available from the site rtfm.mit.edu in plain text
form as ftp://rtfm.mit.edu/pub/usenet-by-group/comp.answers/computer-lang/Modula2-faq/part1
and as ftp://rtfm.mit.edu/pub/usenet-by-group/comp.answers/computer-lang/Modula2-faq/part2

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, to write, 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.


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 2003 10 10 is at  http://www.arjay.bc.ca
Mirrors (for the text, not the FAQ--some may be out of date):
1. TWU Main Site http://www.twu.ca/rsbook/index.html
2. TWU CS Students (Internal only) http://www.csc.twu.ca/rsbook/index.html
3. Brighton, UK  http://burks.bton.ac.uk/burks/index.htm


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 (Component Pascal),
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. The ISO
standard version has OO and Generics. 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 starting in 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. The Object oriented extensions and Generic extensions have
also been voted on and are official. The committee itself has been
disbanded, its work complete.

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 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. In the
meantime, the committee has been disbanded.

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, 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.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++ are making 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 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.)

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 & 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.

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!)

Windows, http://www.medcalc.be, developed using Stony Brook Modula-2,

A7. Finally, the keeper of the FAQ notes that he still gets contracts
to evaluate Modula-2 code in takeover situations and the like.
Details cannot be made public, but include code written for
telecommunication and other automatic systems.


1.12 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. It lends itself
well to software eng
neering. 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 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 Ada or Oberon, and my
second Java (if it ever became cross platform.) If I had to try
teaching beginners C++, I would retire.

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 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


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.

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.

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_Internet/Programming_and_Development/Languages/Modula_2/

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

http://modula2.org

http://cs.ru.ac.za/homes/cspt/modula2.htm

4.2 What other FAQs or lists of pages are available?
A1. http://burks.bton.ac.uk/burks/language/modula2/index.htm
A2. http://dmoz.org/Computers/Programming/Languages/Modula-2/Compilers/ A3http://murray.newcastle.edu.au/users/staff/peter/m2/Modula2.html A4http://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.

A23. 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

4.5 Where can I get a Modula-2 to C converter?
A: The program mtc is available from 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.

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. 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 the Mac 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 at: http://www.arjay.bc.ca


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<!--&#60100; 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
ber 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.



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 o
entering
the extension. You will have to consult the documentation.



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, 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.

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
over seven 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. 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.

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, 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.
