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/modula2 (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 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/ 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/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 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/M= 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 A6.
