 ______________________________________________________________________

 1.  Introduction



 1.1.  What this document is

 This is part four of a seven part document covering many aspects of
 the Forth programming language.  All seven parts are posted monthly to
 the USENET newsgroups comp.lang.forth, comp.answers, and news.answers.
 They are updated regularly.

 This part is primarily concerned with the Forth implementations
 available for a wide variety of systems.  That is, it attempts to
 answer the question, "Where can I get Forth for ...  ?"  For further
 information on Forth or Forth resources, please consult the other
 parts of this FAQ.  They can be found at:


 o  <http://www.forth.org/fig.html>

 o  <ftp://ftp.forth.org/pub/Forth/FAQ/>




 1.2.  What this document is not

 This document is not a complete list of all the available Forth
 implementations, and it never will be.  Neither will it ever be the
 most accurate or up-to-date source for contacts and Forth resources.
 I fully expect to have missed many legacy systems, and I know that
 there are current Forth vendors and authors who have not made it into
 these pages.

 What I have attempted to do is maintain this document as a good
 starting point for those who are interested in finding a Forth
 solution for a given system.

 Just as a single keyword search on the internet may not give you the
 exact results you want, perhaps there are enough "hits" in these pages
 to guide most people to their eventual destination.


 1.3.  How to get the files listed herein

 Some of these Forth systems are listed as being available from
 particular anonymous ftp addresses, or from "good archives".  If you
 have a choice of sites, please try and use as geographically close a
 site to you as possible.  Most ftp directories have README or 00INDEX
 files that tell you what's in them.  Read these first.


 1.4.  Why are some listings so terse?

 Forth is probably one of the most ported languages.  The number of
 implementations I have been able to note in these pages is nothing
 short of staggering.  In some cases I've been forced to be a little,
 um, terse, to say the least.  If this document is going to be accepted
 by most news servers, it has to be kept below a critical size; it may
 already be over that limit for some sites.

 If a listing is short, it is probably because that product is
 available for more than one machine.  If you can't find the Forth
 system you are looking for in this document, please remember that most
 of the vendors mentioned herein can source for a wide variety of
 platforms.  Company addresses and contact information are in part 3 of
 the FAQ, vendors <ftp://ftp.forth.org/pub/Forth/FAQ/vendors>.


 1.5.  Requesting Changes to the FAQ

 There are probably several errors and/or omissions in this document.
 If you spot an error, or feel that there is an obvious omission,
 please let me know <mailto:[email protected]>.  If possible, please send
 one (1) email per change request.

 Please indicate in the email subject line that this is a change
 request for the Forth Systems FAQ, and be sure to include the exact
 text to revise.  It is especially helpful if you can provide an
 example of the new or fixed listing.

 Please note that listings marked with a "?" are known to be wrong, and
 need to be corrected or removed.  As well, I've also marked some
 listings with comments [like this] when I am unsure of the accuracy of
 the information it contains.


 1.6.  About the Systems FAQ

 The source text of this document is in SGML format, and is maintained
 with emacs, utilizing the SGML major-mode. Historical versions are
 stored as a GNU RCS archive.

 The text and HTML versions are created with the SGMLTools package,
 using the LinuxDoc96 DTD. The same tool is used to verify the SGML
 source.

 The HTML 3.2 conversion is tested with Netscape Communicator 4.61 and
 Lynx.  If you require this document in formats other than plaintext or
 HTML, please email me.

 2.2.  To Do

 Maintaining and organizing the comp.lang.forth FAQ is a large job, and
 can eat a big chunk of my time.  I've prioritized some Things To Do to
 let the reader know what I'm up to:


 1. Verify most, if not all, URLs

 2. Organize (and standardize) the internal references, and references
    to the other FAQ-files; integration with HTML versions

 3. Create links for all commercial products to vendors' sites

 4. Update commercial blurbs with latest info

 5. Use the SGML source smarter -- I may or may not continue using the
    idiosyncratic LinuxDoc DTD

 If you want to help, or have any suggestions, please let me know
 <mailto:[email protected]>.



 3.  Forth for Embedded Systems

 Forth is probably the most chip-friendly language there is. I won't
 pretend that I've mentioned even half of the supported chip families.
 Please note that many of the vendors in this section can source for a
 huge variety of chips and chip families.

    Non-commercial

    o  ThisForth
       <ftp://ftp.forth.org/pub/Forth/Compilers/native/unix/this4th.tar.gz>
       v1.0.0.d, by Will Baden, is a reluctantly ANS-compliant C-Forth
       that originated on a Sun Workstation before the ANS-Forth
       standard.  It is intended as an embedded command line
       interpreter and scripting tool for Unix applications.  You will
       need m4 and an ANSI-C compiler to compile it.  Two major design
       objectives were portability and ease of extending.  The first
       goal was achieved by sticking to Standard C, and the Standard C
       Library; the second by the m4 macro processor to define
       primitives in "low-level Forth".  Binaries are available for a
       number of architectures (Macintosh, CRAY, MIPS, SUN, SGI,
       Intel).  [JDV:970407]

    o  PFE (Portable Forth Environment)
       <ftp://ftp.forth.org/pub/Forth/Compilers/native/unix/pfe-0.9.14.tar.gz>
       v0.9.14 is an ANS-compatible Forth implementation written in
       ANSI-C.  All the code is under the GNU Library General Public
       License.  Binaries for various architectures available.  The
       interpreter has many bash-like features, like input completion.
       A more powerful version with dynamic module loading is in final
       testing.  [JDV:02JUN98]

    o  pForth v19 <www.softsynth.com/pforth/> is a public domain,
       portable ANS Forth based on a kernel written in ANSI C.
       designed to be easily portable to any platform, pForth has been
       successfully ported to Macs, PCs, Suns, Amigas, SGI Indys, 3DO
       ARM/PowerPCs and others.  Features ANS standard support for most
       word sets, debugger, DEFER and smart conditionals.  Can be
       compiled without any stdlib calls or special pre-processing.

    o  Gforth <http://www.complang.tuwien.ac.at/forth/gforth/> is a
       fast and portable implementation of the ANS Forth language. It
       works nicely with the EMACS editor, offers some nice features
       such as input completion and history and a powerful locals
       facility, and it even has (the beginnings of) a manual.
       Distributed under the GNU General Public License.  Gforth runs
       under Unix (various flavors), DOS/Win (with GO32), OS/2 (with
       EMX) and Win95/NT, and should not be hard to port to other
       systems supported by GCC.  Gforth-0.1beta
       <ftp://ftp.complang.tuwien.ac.at/pub/forth/gforth/> has been
       tested successfully on Linux (Intel), SunOS (SPARC) and Ultrix
       (MIPS).  Linux binaries

       <ftp://ftp.forth.org/pub/Forth/Archive/ibm/hence4th.arc>; A
       FIGforth written in C that currently runs under V7 Unix,
       Personal C Compiler, and Mix Power C.  Porting to other
       platforms should be trivial, considering how vastly different
       these three are!  [KH:93]

       to call, and be called, by other C functions.  It is ideal as a
       'macro' language embedded in C/C++ applications.  Comes with 175
       pp. of documentation.  [SJB:950720]

    o  |kForth 1.0
       <http://ourworld.compuserve.com/homepages/krishnamyneni/ccre/ccre.htm>
       is available for Linux or Windows.  It implements a subset of
       the ANS-Forth Standard.  Designed such that it's object code may
       be interfaced to another program to serve as a customizable
       application language.  Features include low-level file access
       words, string manipulation and type-checking on memory
       operations.

    Non-commercial

    o  vforth
       <ftp://ftp.forth.org/pub/Forth/Compilers/native/misc/vax/vax-
       forth.tar-z> is a 32-bit forth based on the FIG model, but it
       deviates where necessity or religion demanded.  It will run on a
       VAX running 4.2, and tends to use the UNIX system calls in only
       the most generic of ways (i.e.: it should move to 4.1 without
       problems).  vforth uses subroutine threading and inline code
       generation to increase performance.


    o  John O. Comeau <mailto:[email protected]> has made the
       source
       <ftp://ftp.std.com/pub/jcomeau/hacking/mystuff/vmsfig.bld> and
       documentation
       <ftp://ftp.std.com/pub/jcomeau/hacking/otherstuff/vmsfig.txt>

       [JDV:970510]

    o  Klaus Flesch wrote a VAX VMS Forth some years ago.  It is
       believed to be derived from FIG-Forth.  Availability is
       uncertain; try contacting the author, c/o Forth-Systeme.

    o  There are two files of unknown pedigree at
       <ftp://ftp.forth.org/pub/Forth/Compilers/native/misc/vax/>



 18.  Miscellaneous Forth

 This is a catch-all section for implementations that didn't seem to
 warrant their own sections.


 18.1.  Musical Forth



 o  HMSL (Hierarchical Music Specification Language); Frog Peak Music.
    Contact Delta Research, or Phil Burk <mailto:[email protected]>, at
    the Center for Contemporary Music at Mills College.

 o  MANX 1.0 is an extension of the regular Forth environment, enhanced
    with a number of special purpose music language words.  The program
    is able to read and write standard MIDI files, with special
    instrument drivers taking care of I/O details.  At this moment MANX
    has drivers for metallophones, the PC speaker, and GM (General
    MIDI) synthesizers or sound cards that support MIDI.  This music
    language aims to be complete in the sense that a user should be
    able to translate anything written down in conventional scores to
    MANX commands.  32-bit ANS-Forth, with many extensions.  Free with
    iForth [see the ``32-bit PC Forth'' section].  [JDV:970315]


 18.2.  Java Forth



 o  jeForth <http://www.amsystech.com/mlosh/> is a Java applet based on
    eForth that is free for non-commercial use.  It has been designed
    to be compatible with the description of Forth in Brodie's
    "Starting Forth".  A commercial version is being planned.

 o  Misty Beach Forth <http://www.mistybeach.com/> is an ANS-compliant
    implementation that runs as an OS independent applet.  It is
    designed to run multi-threaded code at speeds comparable to native
    Forths.  The full package will include an IDE.

 o  DELTA Forth is a non-standard Forth system, as it is a compiled
    dialect. It runs on Java, so it is platform-independent.  DELTA
    Forth is free of charge, as it is still in Alpha development stage.
    The most important feature apart from being platform independent is
    that DELTA Forth has support for external libraries, so its
    capabilities are virtually limitless.  Please email the author
    <mailto:[email protected]> for details.



 18.3.  USR/3COM Pilot/Palm Pilot/Palm



    o  Quartus 1.2.1 <http://www.interlog.com/~nbridges> is an on-board
       native ANS Forth optimizing compiler for the USR/3Com Pilot,
       Palm Pilot and Palm III series of PDAs.  Standard precompiled
       (PilRC) resources can be used in your Quartus programs and there
       is built-in compiler awareness of the PalmOS systrap calls.
       There is an evaluation-only version which will not compile code
       to a .prc.




 19.  Forth that ain't necessarily Forth



    Commercial

    o  FIFTH by Software Construction Co.  Available for the Amiga, PC.

    o  Charles Moore's OK for PC's was developed as the OS for Chuck's
       VLSI CAD system.  It is essentially a minimal Graphical User
       Interface (GUI).  Available from Offete Enterprises, Inc.
       <http://www.ultratechnology.com/> Source for the MuP21 Forth
       compiler is also available.

    o  Meme (Multitasking Extensible Messaging Environment) from
       Immersive Systems, Inc. is a Forth interpreter with multitasking
       and floating- point extensions.  The executable has a fast 3D
       rendering engine and a TCP/IP interface that is callable with
       Forth words.  Each object in a Meme virtual world is a
       dynamically-loadable module.  The executable Forth code in the
       modules is a hybrid of token threading and indirect threading
       that is platform-independent and executes identically on any
       computer running the Meme interpreter.  [JDV:960911]


    Non-commercial

    o  Kevo <ftp://cs.uta.fi/pub/kevo/> by Antero Taivalsaari
       <mailto:[email protected]> is a prototypical (classless) object-
       oriented language (for the Mac) which has a Forth feel to it.
       Features multitasking, dynamic memory management, and an
       integrated (Mac Finder-like) iconic programming environment.
       Comes with source, demo programs, and some documentation.
       [AT:931021]

    o  ANNforth
       <ftp://ftp.forth.org/pub/Forth/Compilers/native/unix/annforth.arc>
       by Bruce J. McDonald.  No documentation, but a header file
       states "ANN simulator with forth interpreter".  Written in C++.
       [SJB:931026]

    o  TIPI v2.0a <mailto:[email protected]> is a small, structured,
       extensible programming language for DOS computers.  It requires
       about 100K bytes of RAM to run and is thus well- suited for
       palmtop computers such as the Poquet PC, the HP-95LX or the
       HP100LX.  TIPI incorporates elements from various languages (C,
       Pascal, awk, BASIC) and owes a tremendous amount to Forth.
       While TIPI is not Forth, it is definitely Forth-like and Forth-
       inspired.  A Windows CE version may be in the works.
       [JDV:970723]

    o  FIJI <http://www.well.com/~jax/SoftWoehr/> is a Forthish Java
       interpreter by Jack J. Woehr.
