General Information: This article contains the answers to some
Frequently Asked Questions (FAQ) often seen in
news://comp.lang.prolog/. It is posted (twice a month, currently on
the 2nd and 16th) to help reduce volume in this newsgroup and to
provide hard-to-find information of general interest.
The World Wide Web URL for this FAQ is:
http://www.cs.kuleuven.ac.be/~remko/prolog/faq/
Questions about the FAQ and updates ought to be submitted to
<remko.troncon@cs.kuleuven.ac.be>.
1. What is the Association for Logic Programming?
2. Where can I get a free Prolog for system X (PC, Mac, Unix or
other)?
3. What commercial systems are available? What about systems available
for a price from research institutions?
4. How do I get in touch with my Prolog's users' group, sales
representative, or technical support line?
5. I think language X is better than Prolog. What do you think?
6. What are the recent developments?
7. My Prolog prof assigned me this problem. Can you help me with it?
8. Can you suggest some books on Prolog?
9. Are there any WWW archives of comp.lang.prolog ?
10. How can I get the ISO Prolog standard? Where can I go for more
information about it?

WAM-based compiler or a WAM emulator?
12. Is there a WWW page on logic programming?

1. What is the Association for Logic Programming?
To keep up with the current state of logic programming technology,
readers can join the Association for Logic Programming (ALP) and
receive their Newsletter. For details on how to join or send in
contributions, check http://www.cwi.nl/projects/alp/ or contact
Sandro Etalle <etalle@cs.utwente.nl>
The Prolog Resource Guide (v0.6) was printed in issue 5/1 of the
Newsletter (Feb. 1992). This lists information concerning Prolog
Archives, Books, Suppliers, etc. It is now maintained by Mark
Kantrowitz (<Mark.Kantrowitz@glinda.oz.cs.cmu.edu>), and used to be
posted periodically to news://comp.lang.prolog.
2. Where can I get a free Prolog for system X (PC, Mac, Unix or
other)?
The following are anonymous-FTP sites for free Prologs (or related
languages) which are either in the public domain or are "copy-lefted"
(permitted to be copied with some restrictions on commercial use).
(Please note that for extensive development work, users will probably
want a robust interpreter or compiler with good debugging facilities
and a standard syntax, among other things. While public-domain systems
are a valuable service to the community, they do not necessarily have
all these things, and users should weigh carefully what they want to
do against the capabilities and costs of the available systems.)

3. What commercial systems are available? What about systems available
for a price from research institutions?
Many commercial systems are listed in the Prolog Resource Guide. The
Resource Guide also lists many systems which are not exactly
"commercial", but available for a price from research instutitions.
The list of such systems was originally compiled by Chris Moss, of
Imperial College. The rest of the Resource Guide was originally
compiled by Dag Wahlberg, of Uppsala University.
The Prolog Resource Guide hasn't been updated lately, but nevertheless
still contains some valuable information. It can be found at
http://www-2.cs.cmu.edu/Groups/AI/html/faqs/lang/prolog/prg/top.html.

5. I think language X is better than Prolog. What do you think?
These debates rarely result in any productive discussion. To some
extent, one's favourite language is based on irrational ideology.
However, many people now agree that different languages are good for
different things. Prolog seems to be good for problems in which logic
is intimately involved, or whose solutions have a succinct logical
characterization. Like other interactive, symbolic languages, Prolog
is also good for rapid prototyping.
Also, please note that there are many different "Prologs" and other
logic programming languages available, all with different
capabilities.
6. What are the recent developments?
There are some languages in development which do not have Prolog
syntax, but do subsume and generalize Prolog's logic programming
abilities.

Some other languages bring new developments while also supporting
Prolog syntax and functionality as an option:

7. My Prolog prof assigned me this problem. Can you help me with it?
If your instructor assigned it to you, he or she probably wanted you
to do it yourself. If it's an introductory Prolog course, your
question might be elementary to most readers, so it might be a waste
of network resources to ask it. Please ask your instructor, a friend,
a teaching assistant, or a local newsgroup for help first.
That being said, there are news://comp.lang.prolog/ readers who would
be glad to help people making a legitimate attempt to learn Prolog.
8. Can you suggest some books on Prolog?
The Prolog Resource Guide (see above, question 3) contains a listing
of Prolog books. It is maintained by Mark Kantrowitz
(<Mark.Kantrowitz@glinda.oz.cs.cmu.edu>), and posted periodically on
news://comp.lang.prolog.
Here are some of the most popular books on Prolog.
Introductory
+ "Programming In Prolog". William F. Clocksin and Christopher
S. Mellish. Springer-Verlag, 2003 (5th ed).
+ "Prolog Programming for Artificial Intelligence". Ivan
Bratko. Addison-Wesley, 2001 (3rd ed).
Advanced
+ "The Art of Prolog: Advanced Programming Techniques". Leon
Sterling and Ehud Shapiro. MIT Press, 1994 (2nd ed).
+ "The Craft of Prolog". Richard A. O'Keefe. MIT Press, 1990.
Logic programming theory
+ "Foundations of Logic Programming". John Lloyd.
Springer-Verlag, 1988 (2nd ed).
+ "Logic, Programming and Prolog". Ulf Nilsson and Jan
Maluszynski. Originally published by John Wiley & Sons Ltd
(2nd ed. 1995) but now available without charge from
http://www.ida.liu.se/~ulfni/lpp
Expert Systems
+ "Building Expert Systems in Prolog". Dennis Merritt.
Springer-Verlag, 1989. HTML & PDF versions available from
http://www.amzi.com/ExpertSystemsInProlog
9. Are there any WWW archives of comp.lang.prolog ?
Yes, there are: Google Groups has archives of
news://comp.lang.prolog/. They can be found at
http://groups.google.com/groups?group=comp.lang.prolog
10. How can I get the ISO Prolog standard? Where can I go for more
information about it?
The standard is described in "Prolog: The Standard (Reference
manual)", P. Deransart, A. Ed-Dbali, L. Cervoni, Springer Verlag
(1996). Extra information can be found on
http://pauillac.inria.fr/~deransar/prolog/docs.html
http://www-2.cs.cmu.edu/afs/cs.cmu.edu/project/ai-repository/ai/lang/p
rolog/doc/standard/ contains the December 1991 draft, the March 1993
draft, Richard O'Keefe's 1984 Prolog standard draft, and Michael
Covington's summary of the standard. Note that no one at that site can
answer any questions about the standard; it is just an FTP site for
the standard in the USA.
For more information about the ISO Prolog standard, contact:
Roger Scowen

DITC/93, National Physical Laboratory

Fax: +44 81 977 7091
E-mail: <rss@seg.npl.co.uk>
11. How does the WAM (Warren Abstract Machine) work? How do I write a
WAM-based compiler or a WAM emulator?
Reportedly the best tutorial is Hassan Ait-Kaci's book "Warren's
Abstract Machine: A Tutorial Reconstruction" (MIT Press, 1991).The
book is now OP, but available online at
http://www.vanx.org/archive/wam/wam.html.
12. Is there a WWW page on logic programming?
Yes, there is one by Jonathan Bowen; the URL is
http://www.afm.sbu.ac.uk/logic-prog/. He invites us to mail him at
<jonathan.bowen@sbu.ac.uk> with any relevant information for
inclusion.
13. Can do I do Internet/WWW programming with Prolog?
Prolog is very suitable for this task. Several commercial and free
implementations include special support for it. A page specifically on
this topic (including some tutorials) is maintained at
http://www.clip.dia.fi.upm.es/lpnet/lpnet.html A public-domain library
exists (PiLLoW) for several popular Prolog systems which helps in the
task. See: http://www.clip.dia.fi.upm.es/Software/pillow/
14. Is there a WWW page with some tutorials on prolog?
