This post contains Part 4 of the Lisp FAQ. It is cross-posted to the
newsgroup comp.lang.scheme because it contains material of interest to
Scheme people. The other parts of the Lisp FAQ are posted only to the
newsgroups comp.lang.lisp and news.answers. 

If you think of questions that are appropriate for this FAQ, or would
like to improve an answer, please send email to us at lisp-faq@think.com.

[4-0]   Free Lisp implementations.

Repositories of Lisp source code are described in the answer to
question [6-1]. 

Remember, when ftping compressed or compacted files (.Z, .arc, .fit,
etc.) to use binary mode for retrieving the files.

   Kyoto Common Lisp (KCL) is free, but requires a license. Conforms to CLtL1.
   KCL was written by T. Yuasa <yuasa@tutics.tut.ac.jp> and M. Hagiya
   <hagiya@is.s.u-tokyo.ac.jp> at Kyoto University. Austin Kyoto Common Lisp
   (AKCL) is a collection of ports, bug fixes and improvements to KCL
   by Bill Schelter (<wfs@cli.com> or <wfs@rascal.ics.utexas.edu>). {A}KCL
   generates C code which it compiles with the local C compiler. Both are
   available by anonymous ftp from rascal.ics.utexas.edu [128.83.138.20],
   cli.com [192.31.85.1], or [133.11.11.11] (a machine in Japan)
   in the directory /pub. KCL is in the file kcl.tar, and AKCL is in the
   file akcl-xxx.tar.Z (take the highest value of xxx).  To obtain KCL, one 
   must first sign and mail a copy of the license agreement to: Special 
   Interest Group in LISP, c/o Taiichi Yuasa, Department of Computer Science,
   Toyohashi University of Technology, Toyohashi 441, JAPAN. Runs on Sparc,
   IBM RT, RS/6000, DecStation 3100, hp300, hp800, Macintosh II (under AUX),
   mp386, IBM PS2, Silicon Graphics 4d, Sun3, Sun4, Sequent Symmetry,
   IBM 370, NeXT and Vax. A port to DOS is in beta test as
   math.utexas.edu:pub/beta2.zip. Commercial versions of {A}KCL are available
   from Austin Code Works, 1110 Leafwood Lane, Austin, TX 78750-3409,
   Tel. 512-258-0785, Fax 512-258-1342, including a CLOS for AKCL.
   See also Ibuki, below.

   XLISP is free, and runs on the IBM PC (MSDOS), Amiga (AmigaDOS),
   Atari ST (TOS), Apple Macintosh, and Unix. It should run on
   anything with a C compiler.  It was written by David Michael Betz,
   167 Villa Avenue #11, Los Gatos, CA 95032, 408-354-9303 (H), 
   408-862-6325 (W), dbetz@apple.com. The reference manual was
   written by Tim Mikkelsen. Version 2.0 is available by anonymous ftp from
           cs.orst.edu:/pub/xlisp/ [128.193.32.1] or
           sumex-aim.stanford.edu:info-mac/lang/
   Version 2.1 is the same as XLISP 2.0, but modified to bring it closer
   to Common Lisp and with several bugs fixed. It can be obtained by
   anonymous ftp from
                   glia.biostr.washington.edu      128.95.10.115
                   bikini.cis.ufl.edu              128.227.224.1
   in the file xlisp21d.zip and comes with IBM/PC executables. For obtaining
   a copy through US mail, send email to Tom Almy, toma@sail.labs.tek.com.

   CMU Common Lisp is free, and runs on Sparcs (Mach and SunOs),
   DecStation 3100 (Mach), IBM RT (Mach) and requires 16mb RAM, 25mb
   disk. It includes an incremental compiler, Hemlock emacs-style editor,
   source-code level debugger, code profiler and is mostly X3J13
   compatible, including the new loop macro.  It is available by anonymous
   ftp from any CMU CS machine, such as ftp.cs.cmu.edu [128.2.206.173], in the
   directory /afs/cs.cmu.edu/project/clisp/release. Login with username
   "anonymous" and "userid@host" (your email address) as password. Due to
   security restrictions on anonymous ftps (some of the superior
   directories on the path are protected against outside access), it is
   important to "cd" to the source directory with a single command.
   Don't forget to put the ftp into binary mode before using "get" to
   obtain the compressed/tarred files. The binary releases are
   contained in files of the form
                <version>-<machine>_<os>.tar.Z
   Other files in this directory of possible interest are
   16e-source.tar.Z, which contains all the ".lisp" source files
   used to build version 16e. A listing of the current contents of the
   release area is in the file FILES. You may also use "dir" or "ls" to 
   see what is available. Bug reports should be sent to cmucl-bugs@cs.cmu.edu.

   PC LISP is a Lisp interpreter for IBM PCs (MSDOS) available from any
   site that archives the group comp.binaries.ibm.pc, such as
   ix1.cc.utexas.edu:/microlib/pc/languages/pc-lisp/ps-lisp.arc
   wuarchive.wustl.edu:/mirrors/msdos/lisp/pclisp30.zip 
   ucdavis.ucdavis.edu:/pub/pclisp30.zip
   PC-LISP is a Franz LISP dialect and is by no means Common LISP
   compatible. It is also available directly from the author by sending
   2 blank UNFORMATTED 360K 48TPI IBM PC diskettes, a mailer and
   postage to: Peter Ashwood-Smith, 8 Du Muguet, Hull, Quebec, CANADA,
   J9A-2L8; phone 819-595-9032 (home). Source code is available from the
   author for $15.

   WCL is an implementation of Common Lisp for Sparc based workstations.
   It is available free by anonymous ftp from sunrise.stanford.edu in the
   pub/wcl directory. The file wcl-2.14.tar.Z contains the WCL
   distribution, including CLX and PCL; wgdb-4.2.tar.Z contains a version
   of the GDB debugger which has been modified to grok WCL's Lisp; and
   gcc-2.2.2.tar.Z contains the GNU C compiler.  WCL provides a large
   subset of Common Lisp as a Unix shared library that can be linked with
   Lisp and C code to produce efficient and small applications.  WCL
   provides CLX R5 as a shared library, and comes with PCL and a few
   other utilities.  For further information on WCL, see the paper
   published in the proceedings of the 1992 Lisp and Functional
   Programming Conference, a copy of which appears in the wcl directory
   as lfp-paper.ps, or look in the documentation directory of the WCL
   distribution. Please direct any questions to Wade Hennessey,
   wade@sunrise.stanford.edu. If you would like to be added to a
   mailing list for information about new releases, send email to
   wcl-request@sunrise.stanford.edu. 

   CLISP is a Common Lisp (CLtL1) implementation by Bruno haible and
   Michael Stoll of Karlsruhe University in Germany. German and English
   versions are available. It runs on Atari-ST, DOS, Linux, and Sun4
   (SunOS 4.1.1), An OS/2 port is in progress. CLISP is for non-profit
   use at universities and at home, not at companies. It includes an
   interpreter and a compiler. Some of the implementations may be
   slightly buggy. Some include PCL; others include only Closette.
   Available by anonymous ftp from ma2s2.mathematik.uni-karlsruhe.de in
   the directory /pub/lisp/clisp. For more information, contact
   haible@ma2s2.mathematik.uni-karlsruhe.de.

Other Lisps for PCs include: 
   o  UO-LISP from Calcode Systems, e-mail:calcode!marti@rand.org
      It comes complete with compiler and interpreter, and is optimised for
      large programs.  It is Standard LISP, not Common LISP. They are based
      in Amoroso Place in Venice, CA. 
   o  LISP/88 v1.0. Gotten from Norell Data Systems, 3400 Wilshire Blvd,
      Los Angeles, CA 90010, in 1983. They may or may not still exist. 
   o  IQLisp. Not a Common Lisp but still very good for PCs - you can
      actually get a lot done in 640K.  The lisp itself runs in less than
      128K and every cons cell takes only 6 bytes.  Unfortunately that
      makes the 640K (maybe a little more, but certainly no more than 1M)
      limit really hard. It has a byte code compiler which costs extra. 
      This has support for all sorts of PC specific things.
      It costs $175 w/o compiler, $275 with.

[4-2]   Free Scheme implementations.

Repositories of Scheme source code are described in the answer to
question [6-2].

Remember, when ftping compressed or compacted files (.Z, .arc, .fit,
etc.) to use binary mode for retrieving the files.

   Many free Scheme implementations are available from altdorf.ai.mit.edu
   [18.43.0.246]. See also the Scheme Repository described below.

   The Scheme Repository contains a Scheme bibliography, copies

   PCS/Geneva is a cleaned-up version of Texas Instrument's PC Scheme
   developed at the University of Geneva. The main extensions to PC
   Scheme are 486 support, BGI graphics, LIM-EMS pagination support, line
   editing, and assmebly-level interfacing. (TI's PC Scheme gives users
   full Revised^3 support along with many primitives for DOS, Graphics
   and Text Windows. A powerful built-in optimizing compiler produces
   fast code.) The beta version of PCS/Geneva has been tested on XTs,
   ATs, AT386s and AT486s under various DOS and OS/2 versions. It
   even runs on Hewlett-Packard's HP95LX. To receive a copy of
   PCS/Geneva, please send email to schemege@uni2a.unige.ch. You will be
   given instructions on obtaining PCS/Geneva by FTP. The purpose of the 
   mailing detour is to keep track of the users and diffuse bug reports along
   with corrections.

[4-4]   Other Commercial Lisp-like Language implementations.

   Le-Lisp includes a compiler, color and graphic output, a debugger, a
   pretty printer, performance analysis tools, tracing, and incremental
   execution. Le-Lisp is Macintosh AUX 2.0 Compatible and also runs on
   Unix platforms. Note that Le-Lisp is neither Common Lisp nor Scheme.
   Le-Lisp was originally developed in 1980 at Inria, the French national
   computer science laboratory, by a team led by Jerome Chailloux for
   work on VLSI design. It was based on several earlier Lisps in the
   MacLisp family, but was not directly derived from MacLisp.  Le-Lisp
   enjoyed a large success in the French academic world because it was
   small, fast, and portable, being based on a abstract machine language
   called LLM3.  In 1983, for example, Le-Lisp ran on Z-80 machines
   running CP/M. In 1987, Ilog was formed as an offshoot of Inria to
   commercialize and improve Le-Lisp and several products which had been
   developed with it, including a portable graphic interface system and an
   expert system shell.  Since then, Ilog has continued to grow and
   expand the use of Le-Lisp into industrial markets around the world.
   Ilog is the largest European Lisp vendor, and continues to develop new
   products and markets for Lisp.  In 1992, Ilog released the next major
   version of Le-Lisp, Le-Lisp version 16.  This version modernizes
   Le-Lisp for use in the industrial world, adding lexical closures and
   special-form-based semantics for static analysis, a new object system
   based on the EuLisp object system (TELOS), an enhanced module system
   for application production, a conservative GC for integration with C
   and C++, and compilation to C for portability and efficiency on a wide
   range of processors. For pricing and other information, write to

[4-5] Where can I get an implementation of Prolog in Lisp?

Implementations of Prolog in Lisp:

   The Frolic package from the University of Utah is written in Common Lisp
   and available by anonymous ftp from cs.utah.edu:pub/frolic.tar.Z
     
   Prolog in Scheme is a collection of macros that expand syntax for
   clauses, elations, and so on. It is written in Scheme and has support
   for delayed goals and interval arithmetic. It is known to run in Chez
   Scheme and in Elk, and is intended to be portable to other Scheme
   implementations. It relies on continuations, and so is not easily
   ported to Common Lisp. Available from the University of Calgary by
   anonymous ftp from
      fsa.cpsc.ucalgary.ca:pub/prolog1.2/prolog12.tar.Z
   Questions and comments may be addressed to Alan Dewar
   <dewar@cpsc.ucalgary.ca> or John Cleary <cleary@cpsc.ucalgary.ca>.
     
   An implementation of prolog for Chez Scheme is available by anonymous
   ftp from titan.rice.edu:public/slog.sh. It is a collection of macros
   that expand syntax for clauses, elations, and so on into pure Scheme.
   It should be easily portable to other Schemes.  Its use of
   higher-order continuations is probably a major obstacle to porting it
   to Common Lisp.  For more information, please contact the author:
   dorai@cs.rice.edu.
     
   LM-PROLOG by Ken Kahn and Mats Carlsson is written in ZetaLisp and not
   easily portable to Common Lisp. It is available by anonymous ftp from
   sics.se:archives/lm-prolog.tar.Z.
     
   Peter Norvig's book "Paradigms of AI Programming" includes Common Lisp
   implementations of a prolog interpreter and compiler. The software is
   available by anonymous ftp from unix.sri.com:pub/norvig and on disk in
   Macintosh or DOS format from the publisher, Morgan Kaufmann.  For more

[4-6] What is Dylan?

Dylan is a new object-oriented dynamic language (oodl), based on Scheme, CLOS,
and Smalltalk.  The purpose of the language is to retain the benefits of oodls
and also allow efficient application delivery.  The design stressed keeping
Dylan small and consistent, while allowing a high degree of expressiveness. A
manual/specification for the language is available from Apple Computer.  Send
email to dylan-manual-request@cambridge.apple.com or write to Apple Computer, 1
Main Street, Cambridge, MA 02142.  Include your complete address and also a
phone number (the phone number is especially important for anyone outside the
US). Comments on Dylan can be sent to the internet mail address
dylan-comments@cambridge.apple.com. 

The mailing list info-dylan@cambridge.apple.com is for any and all
discussions of Dylan, including language design issues, implementation
issues, marketing issues, syntax issues, etc. The mailing list
announce-dylan@cambridge.apple.com is for major announcements about
Dylan, such as the availability of new implementations, new versions
of the manual, etc.  This mailing list should be *much* lower volume
than info-dylan.  Everything sent to this list is also sent to
info-dylan.  The mailing list dylan-builders@cambridge.apple.com is
for people who are working on Dylan implementations. (To be added to
dylan-builders, send a note describing your implementation plans to
dylan-builders-request.) Apple hopes to set up a comp.lang.dylan
newsgroup to be gatewayed to the info-dylan mailing list.

Send mail to the -request version of the list to be added to it.

Apple hasn't announced plans to release Dylan as a product.  

The directory cambridge.apple.com:pub/dylan contains some documents
pertaining to Dylan, including a FAQ list.

language" by Apple Computer Eastern Research and Technology, April
1992. Thomas was written at Digital Equipment Corporation's Cambridge
Research Laboratory. Thomas is NOT Dylan(TM) and was built with no
direct input, aid, assistance or discussion with Apple.

Thomas is available to the public by anonymous ftp at
       crl.dec.com:pub/DEC/Thomas
       gatekeeper.pa.dec.com:pub/DEC/Thomas
       altdorf.ai.mit.edu:archive/Thomas

The Thomas system is written in Scheme and runs under MIT's CScheme,
DEC's Scheme->C, and Marc Feeley's Gambit.  It can run on a wide range
of machines including the Macintosh, PC compatibles, Vax, MIPS, Alpha,
and 680x0.  Thomas generates IEEE compatible Scheme code.

DEC CRL's goals in building Thomas were to learn about Dylan by
building an implementation, and to build a system they could use to
write small Dylan programs. As such, Thomas has no optimizations of
any kind and does not perform well. 

The original development team consisted of:
          Matt Birkholz (Birkholz@crl.dec.com)
          Jim Miller (JMiller@crl.dec.com)
          Ron Weiss (RWeiss@crl.dec.com)
In addition, Joel Bartlett (Bartlett@wrl.dec.com), Marc Feeley
(Feeley@iro.umontreal.ca), Guillermo Rozas (Jinx@zurich.ai.mit.edu)
and Ralph Swick (Swick@crl.dec.com) contributed time and energy to the
initial release.

[4-7] What Lisp-related discussion groups and mailing lists exist?
     
Before posting to any discussion group, please read the rest
of this FAQ, to make sure your question isn't already answered.
     
First of all, there are several lisp-related newsgroups:
   comp.lang.lisp          General Lisp-related discussions.
                           See below for archive information.
   comp.lang.clos          Discussion related to CLOS, PCL, and
                           object-oriented programming in Lisp.
                           Gatewayed to commonloops@cis.ohio-state.edu.
                           (or equivalently, comp.lang.clos@cis.ohio-state.edu)
                           See below for info on the newsgroup's archives.
   comp.lang.lisp.mcl      Discussions related to Macintosh
                           Common Lisp. This newsgroup is gatewayed
                           to the info-mcl@cambridge.apple.com
                           mailing list and archived on cambridge.apple.com.
   comp.lang.lisp.franz    Discussion of Franz Lisp, a dialect of Lisp.
                           (Note: *not* Franz Inc's Allegro.)
   comp.lang.lisp.x        Discussion of XLISP, a dialect of Lisp.
   comp.sys.xerox          Discussions related to using Medley (name exists
                           for historical reasons, and is likely to change
                           soon). Gatewayed to the info-1100 mailing list.
   comp.windows.garnet     Garnet, a Lisp-based GUI.
   comp.lang.scheme        General Scheme-related discussion.
                           This newsgroup is gatewayed to the
                           scheme@mc.lcs.mit.edu mailing list.
   comp.lang.scheme.c      Discussion of C-Scheme, a scheme dialect.
                           This newsgroup is gatewayed to the
                           info-cscheme@zurich.ai.mit.edu mailing list.
   comp.ai and subgroups   General AI-related dicusssion.


The newsgroup comp.lang.lisp is archived on ftp.gmd.de by month, from
1989 onward. Individual files are in rnews format. (They contain
articles prefixed by a header line "#! rnews <nchars> archive" where
<nchars> is the number of characters in the article following the
header. That format is convenient for various news processing programs
(e.g.  relaynews) and is rather easy to process from a lisp program too.)
A copy of the GMD archives for comp.lang.lisp is available on
cambridge.apple.com:pub/comp.lang.lisp.

[4-8]   What are R4RS and IEEE P1178?

R4RS is the Revised^4 Report on the Algorithmic Language Scheme,
edited by W. Clinger and J. Rees. It appeared in ACM Lisp Pointers IV,
July-September 1991, and also as MIT AI Memo 848b. It serves as a kind
of standard for the language. It can be obtained by anonymous ftp at
the two Scheme Repositories, altdorf.ai.mit.edu and nexus.yorku.ca.

IEEE P1178 is IEEE Standard 1178-1990, "IEEE Standard for the Scheme
Programming Language", published by IEEE in 1991. ISBN 1-55937-125-0.
It is now also an ANSI standard. It may be ordered from IEEE by
calling 1-800-678-IEEE and using order number SH14209.
----------------------------------------------------------------
[4-9]   How do I do object-oriented programming in Scheme?

Some Scheme implementations (for example, MacScheme, Feel, Oaklisp,
and PC-Scheme) include built-in object-oriented extensions.  

The MEROON package is a mini-CLOS-like object package for generic R4RS
Scheme (but with non-standard macros). It runs with PC-Scheme,
Scheme->C and Chez Scheme. It is available in the Scheme Repository as
nexus.yorku.ca:pub/scheme/new/meroon.*.tar.Z. A paper on it appears in
nexus.yorku.ca:pub/txt/meroon.ps.Z.

For information on YASOS (Yet Another Scheme Object System), see
"Scheming with Objects" in the October 1992 issue of AI Expert magazine.
