Modula-3 Frequently Asked Questions
===================================
What is Modula-3 ?
The goal of Modula-3 is to be as simple and safe as it can be while
meeting the needs of modern systems programmers. Instead of
exploring new features, we studied the features of the Modula
family of languages that have proven themselves in practice and
tried to simplify them into a harmonious language. We found that
most of the successful features were aimed at one of two main
goals: greater robustness, and a simpler, more systematic type
system.
Modula-3 descends from Mesa, Modula-2, Cedar, and Modula-2+. It
also resembles its cousins Object Pascal, Oberon, and Euclid.
Modula-3 retains one of Modula-2's most successful features, the
provision for explicit interfaces between modules. It adds objects
and classes, exception handling, garbage collection, lightweight
processes (or threads), and the isolation of unsafe features.
Is Modula-3 a superset of Modula-2 ?
No; valid Modula-2 programs are not valid Modula-3 programs.
Where can I get a description of Modula-3 ?
The definition of Modula-3 is contained in:
System Programming with Modula-3
Edited by Greg Nelson
Prentice Hall Series in Innovative Technology
ISBN 0-13-590464-1
L.C. QA76.66.S87 1991
also known as SPwM3. Here is the table of contents:
1. Introduction
2. Language Definition
3. Standard Interfaces
4. An Introduction to Programming with Threads
5. Thread Synchronization: A Formal Specification
6. I/O Streams: Abstract Types, Real Programs
7. Trestle Window System Tutorial
8. How the Language Got its Spots
Chapters 2 and 3 have been reprinted in Sigplan Notices, Volume 27,
Number 8, August 1992, pp 15-42.
Sam Harbison has written a book about Modula3:
Modula-3
Samuel P. Harbison
Prentice Hall, 1992
ISBN 0-13-596396-6
as well as an overview article, "Modula-3", in Byte, Vol. 15,
Number 12, October 1990, p 385.
Where can I get information on Modula-3 ?
There is a Usenet newsgroup, comp.lang.modula3. The archives of
that group are available via anonymous ftp from gatekeeper.dec.com
in pub/DEC/Modula-3/comp.lang.modula3. If you do not have
access to Usenet, there is a relay mailing list; send a message to
m3-request@src.dec.com to be added to it.
Where can I get an implementation ?
There is only one implementation available today. It has been built
by SRC and is available via anonymous ftp from gatekeeper.dec.com in
pub/DEC/Modula-3/release. Contributed software can be found
in pub/DEC/Modula-3/contrib.
The current version, 2.07, implements the language defined in SPwM3.
There are versions for the following machines:
AIX386 IBM PC running AIX/PS2,
AP3000 Apollo DN4500 running Domain/OS
ARM Acorn R260 running RISC iX 1.21
DS3100 DECstation 3100 and 5000 running Ultrix 4.0 and 4.2
HP300 HP 9000/300 running HP-UX 8.0
IBMR2 IBM R6000 running AIX 3.1,
IBMRT IBM RT running IBM/4.3,
NEXT NeXT running ?
SPARC SPARCstation running SunOS 4.1.x
SUN3 SUN3 running SunOS
UMAX Encore Multimax running UMAX 4.3 (R4.1.1)
VAX VAX running Ultrix 3.1
SRC Modula-3 includes a user manual, compiler, runtime library,
some libraries and a few other goodies (see below).
The compiler generates C as an intermediate language and should be
fairly easy to port. Except for the very lowest levels of the
thread implementation, the entire system is written in Modula-3.
What if I don't have ftp access ?
Unfortunately, we cannot deliver Modula-3 other than by
anonymous ftp. Your best bet is to post a message to
comp.lang.modula3, in the hope that somebody with ftp
access can make a tape or floppy for you.
Can I contribute Modula-3 software ?
Certainly. Send us what you are willing to share, be it programs,
libraries or other things. We'll put them in the distribution.
