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 [e-mail].

[4-0] Where can I get/buy Lisp and Scheme for the ... architecture?

There are many implementations of Lisp and Scheme interpreters and
compilers, about half of which are available free and the rest are
available commercially.

Repositories of Lisp/Scheme source code are described in the answer to
question [2-0].

Free Lisp implementations:

   Kyoto Common Lisp (KCL) is free, but requires a license. Conforms to CLtL1.
   KCL was written by T. Yuasa <[e-mail]> and M. Hagiya
   <[e-mail]> at Kyoto University. Austin Kyoto Common Lisp
   (AKCL) is a collection of ports, bug fixes and improvements to KCL
   by Bill Schelter (<[e-mail]> or <[e-mail]>). {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. [phone], Fax [phone], 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), [e-mail]. 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 xlisp21c.zip (soon xlisp21d.zip) and comes with IBM/PC
   executables. For obtaining a copy through US mail, send email to Tom
   Almy, [e-mail].

   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 [e-mail].

   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
   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 [phone] (home).

   Elk (Extension Language Kit) is a Scheme interpreter designed to be
   used as a general extension language. Available by anonymous ftp from
   the Scheme Repository in nexus.yorku.ca:/pub/scheme/imp/.  Also
   available in the X contrib directory on export.lcs.mit.edu. Runs on
   Unix, SunOs, and Ultrix based platforms, including VAX, Sun3, Sun4
   (Sparc), 680x0, 80386, MIPS, and IBM RT. The Elk interpreter is mostly
   R3RS compatible. Elk has interfaces to Xlib, Xt and the various widget
   sets.  Implemented by Oliver Laumann.

   EuLisp is available from gmdzi.gmd.de [129.26.8.90] in the
   /lang/lisp/eulisp directory.

   eulisp language. It can be retrieved by anonymous FTP from ftp.bath.ac.uk
   in the directory /pub/eulisp/ as the file feel-0.75.tar.Z. feel-0.75.sun4.Z
   is the Sparc executable. The language definition is in the same directory.
   It includes an integrated object system, a module system, and
   support for parallelism. The program is a C-based interpreter, and a
   bytecode interpreter/compiler will be available sometime soon.
   The distribution includes an interface to the PVM library, support
   for TCP/IP sockets, and libraries for futures, Linda, and CSP.
   Feel is known to run on Sun3, Sun4, Stardent Titan, Alliant Concentrix
   2800, Orion clippers, DEC VAX, DECstation 3000, Gould UTX/32, and Inmos
   T800 transputer (using CS-Tools). (All bar the last four have a threads
   mechanism.) It can run in multi-process mode on the first three
   machines, and hopefully any other SysV-like machine with shared
   memory primitives. Porting Feel to new machines is reasonably
   straightforward. It now also runs on MS-DOS machines.
   Written by Pete Broadbery, [e-mail].

   HELP (a lazy Scheme) is available by anonymous ftp from
   sumex-aim.stanford.edu:/info-mac/lang/lazy-scheme.hqx.  Written by
   Thomas Schiex ([e-mail], [e-mail]). Help is a complete and
   efficient Scheme-like functional lazy Lisp interpreter.  It works only
   on 68020 (or more) based Macintoshes. It has a 'friendly' interface
   (parenthesis matcher, auto-indent), uses a full call-by-need semantics
   and includes many examples, including a symbolic compiler for the
   680x0. Efficiency is good and lazyness is fully parametrizable (you
   main turn Help into a strict Scheme-like language if you like). French
   AND English updated docs are included in Word4 and plain text formats.


Free Scheme Implementations implemented in Lisp:

   implemented on top of Common Lisp, and runs in Lucid, Symbolics CL,
   VAX Lisp under VMS, and Explorer CL. It should be easy to port to
   other Lisps. It was written by Jonathan Rees ([e-mail],
   [e-mail]). Send mail to [e-mail]
   to be put on a mailing list for announcements. Conforms to R3RS except
   for lacking a correct implementation of call/cc. It works by running
   the Scheme code through a preprocessor, which generates Common Lisp code.

   Scheme88 is available by anonymous ftp from rice.edu:public/scheme88.sh

      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.

[4-1] 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 Prolog interpreter available from the
   University of Calgary. 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 by anonymous ftp from
      fsa.cpsc.ucalgary.ca:pub/prolog1.2/prolog12.tar.Z
   Questions and comments may be addressed to Alan Dewar
   <[e-mail]> or John Cleary <[e-mail]>.

   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:
   [e-mail].

   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
   information, contact: Morgan Kaufmann, Dept. P1, 2929 Campus Drive, Suite
   260, San Mateo CA 94403, [phone]; FAX: [phone]

[4-2] 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 [e-mail] 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
[e-mail].

Apple hasn't announced plans to release Dylan as a product.  Also there is
no two way mailing list for discussing Dylan at this time.

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

[4-4]   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.
----------------------------------------------------------------
[4-5]   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.
