                 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/Lan=
guages/Modula_2/

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

http://modula2.org

http://lwb.mi.fu-berlin.de/murus/A large amount of Modula-2 source as well =
as the modified Mocka-on-Linux compiler (to accept def/mod files).


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://freepages.modula2.org

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/   (Eastern Europe).

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

A2. LMathLib is a library that defines a number of mathematical functions f=
or Modula 2 programs. Unlike other libraries of the same kind, LMathLib pat=
ches the Modula 2 compiler. All library functions are inlined as assembler =
code for the Floating Point Unit. This results in faster code compared to t=
he traditional solution with subroutine calls. Due to this machine dependen=
t 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 fo=
r Canterbury M2 is freely downloadable from http://www.webcom.com/mhc/welco=
me.html
Features:
 Written fully in INTEL CPU machine language

  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/
ftp://ftp.Uni-Koeln.DE/usenet/comp.archives/languages/modula-2/mtc/
Several of the compilers available work or can work by producing C or C++ c=
ode and can also serve this purpose. See p1, XDS and Ulm's m2c (not the sam=
e as mtc) listings for examples.

4.6  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 us=
e any CP specific features, i.e. generates standard Oberon-2.

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


4.8 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 scanner=
s from attribute grammars. Full source code, and a variety of simple exampl=
e 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/Coc=
o/ 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/
ftp://cs.ru.ac.za:/pub/
ftp://ftp.fit.qut.edu.au:/pub/
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 compile=
r 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 Compi=
ler Generators" that uses Coco/R is now online at http://www.scifac.ru.ac.z=
a/compilers

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

4.9 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/platfor=
ms/pc/windows/programming/modula/m2afx.zip

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

4.10 Does there exist something to convert a C header file to a Modula-2 DE=
FINITION MODULE file for me?
A. Try looking at the XDS Ltd site for the H2D freeware product on some pla=
tforms

4.11 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.

4.12 What language is the linker written in?

A. That depends. If the linker is system wide (designed for multiple langua=
ges) it could be written in almost any language. If it icomes with the Modu=
laq-2 package and is designed for linking files produced by a Modula-2 comp=
iler, it may well be written in Modula-2.


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 Stadle=
r, 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 f=
or non-commercial purposes. mailto:cadamuller@swissonline.ch

4.16 Is C. Lins SCL library available?

A. Yes, at



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

A2. Here are two answers submitted to the newsgroup in response to a desper=
ate student's plea for ANY Modula-2 program. The first is rather prosaic; t=
he 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=3D0; i100; i++)
        printf("I will do my own homework.\n");

}

Followup Question: Is that Modula-2? I just finished my first course in Mod=
ula-2 and that don't look at all familiar. I'm not looking forward to the f=
inal exam.
A. (Pat Terry) Computer Science changes sooo rapidly. Haven't you discovere=
d 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 Generato=
rs, Communications of the ACM, vol. 31, no. 6, pp. 742-749. The RNG has a p=
eriod of approximately 2.3E+18. Generating 1 000 000 numbers per second, th=
at 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 num=
ber generator' described by Park & Miller, CACM 31,10,Oct 88 p1192. The cod=
e has been checked for the 10001st random as specified in Park & Miller p11=
95. 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://ww=
w.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 =3D)...etc.

Because Modula-2 has short circuited Boolean expression evaluation, the fir=
st part guards the second from being evaluated inappropriately. Then, take =
the radical, unC-like step of checking your code design for the logical err=
or 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 delin=
eated 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. Declar=
ing 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 (TYP=
E) 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 y=
ou 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 multidi=
mensional arrays of LOC, and there are no defined BYTE and WORD types, thou=
gh 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 s=
tandard. 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) o=
bjects 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 t=
hat are in the structure or the target of the routine. The initial module i=
s called a generic module. Such modules can be refined for the specific dat=
a 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 Termin=
al.

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 requi=
re 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 w=
ay 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 t=
he 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 do=
ing. For instance, if there were no colon in a type declaration, the compil=
er 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 h=
ere.



6. WHAT ARE SOME REFERENCE MATERIALS ON MODULA-2?

A1. A shareware text I have written (and that MAY be the only currently mai=
ntained English language instructional text on Modula-2) is available. See =
section 1.41.4.
A2.The manuals for some of the commercial products contain much useful info=
rmation.

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/
odula2.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, /do=
c/tech-reports and /pub/oberon/docu

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 pu=
blication. I have been a member of the ISO committee WG13 (Modula-2 standar=
dization) 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 di=
rected an implementation of the ISO I/O library in order to verify its conc=
epts. 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 manuf=
acturer or distributor of software. I am the author of some Modula-2 materi=
als (some of which are shareware) as noted herein, and of various other boo=
ks. Some manufacturers may distribute my shareware on CD-ROM for a previous=
ly 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 f=
or TWU, WG13, ABC, IEEE, ACM, comp.lang.modula2, the GNU or Objective Modul=
a-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 a=
nd factual content and is otherwise entirely without prejudice. I reserve t=
he right to edit all submissions for brevity, clarity, and usage.
