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/>. 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:firstname.lastname@example.org>. 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. Recent Changes 2.1.

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@example.com>. 3.

Commercial [I am currently unaware of any commercial VAX/VMS Forth --jdv] Non-commercial o vforth <ftp://ftp.forth.org/pub/Forth/Compilers/native/misc/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:firstname.lastname@example.org> has made the source <ftp://ftp.std.com/pub/jcomeau/hacking/mystuff/> and documentation <ftp://ftp.std.com/pub/jcomeau/hacking/otherstuff/> for versions 1 & 2 of FIG-Forth for the VAX/VMS available. [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@example.com>, 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:firstname.lastname@example.org> 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@example.com> 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/> 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:firstname.lastname@example.org> 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. 20.
