    • Facebook "Forth2020 Users-Group", Thread "How does one get an operational Forth system on a board that has extremely limited SRAM?" - “BTW, I”d consider using an Alphabetical Letter Forth bytecode: I've mapped the most common names in forth to 1 letter, and others to two letter sequences. I went through all the standard forth words and extras and assigned them 1-2 letters. I feel the mapping is pretty good. The mapping/bytecode was created for a letter byte coded forth for 6502 (not completed, but experiemnted on in various variants). There are many nice features with having the byte-code be the same the names. You'll find a number of similar systems of various “forth” charactersistcs by other members. What I've learned is that this simplifies, if not completely removes the need for a compiler/parser. I made a prototype one, with 8 bit (byte) “wordsize” with an editor. 256 bytes housed all user defined words (address 0-N, 0 terminated). and the end of the 256 byte page was 16 bytes for program stack, 16 bytes for user stack. The program grew up towards the stack that grew down”.
    • “I almost had a fullscreen (vt100) editor working for the 256– bytes. Newlines-formatted.256 bytes quite a lot of op-codes... CTRL-R reset the stack and parsed worddefs/ran the code on screen.Instead of immediate/Compile mode I had Edit/Run mode. I think my 50+ words plus editor was about 1.5KB in 6502”.

          • Installation and operation with the C64 emulator “C64 Emulator”:
            • It is not useful to create a “Game Exe” by the menu command “Configuration / Misc / Create Game Exe” and selecting the disk image “vforth4_1.d64” as application, as loading a disk causes the error message ”?DEVICE NOT PRSENT ERROR”.
            • Instead, load a the disk image “vforth4_1.d64” by menu command “Configuration / Load File”. The loaded disk is be available even after executing the “Reset” menue command of the emulator.
            • At C64-BASIC promt:
              • Press “F1” key. It executes the C64-BASIC command 'LOAD”$”,8'.
              • “LIST” lists the directory of the loaded volksFORTH disk.
              • Execute 'LOAD”RUNME”,8' to read the readme text.
              • Execute 'LOAD”C64-VOLKSFORTH83”,8' to load volksFORTH.
              • Execute “RUN” to start volksFORTH.

          • Installation and first-time operation with the ATARI-ST emulator “Hatari”:
            • Copy the contents of the “Harddisk” directory of the volksForth distribution archive on your host filesystem.
            • Press “F12” to enter the Hatari main menu.
            • Select “Atari screen” to configure the graphics resolution, e.g. to switch to “Mono”. Press the button “Back to main menu”.
            • Select “Hard disks”. Click on “GEMDOS drive: Browse” to select the “Harddisk” directory on your host filesystem. Press the button “Back to main menu”.
            • Optional saving of the configuration.
              • Select “Save config”. Select a directory with the configuration file “hatari.nvram”, click on the “hatari.nvram” filename label and press the button “ok”. The default file path on Win10 is “C:\users\<user>\AppData\Local\Hatari\hatari.nvram”.
              • As with “Hatari 2.3.1”, however, by saving a configuration, neither the screen size nor the GEMDOS drive can be restored by this.

    • Facebook "FORTH PROGRAMMING / EARLY FORTH SYSTEMS & DEVELOPMENT", Thread "How to handle parser recursion when dealing compiled Forth words?" - ” The minimal CP/M VolksForth kernel has access to the first file that you give as parameter on the command line. So if you run “volks4th fileint.fb” then all block access goes to the block file fileint.fb. If you then, inside VolskForth, run '1 load' then you have the full file interface available, with USE, INCLUDE etc. Without fileint.fb loaded, you have access to only that one file passed from the CP/M command line”.

bForth & eForth Design Principles
  • Chen-Hanson Ting told me in 2021-08:
    • The original Forth of Chuck Moore of 1970 had the concept of a virtual memory system, i.e. the concept to read and write tapes, to save binary data to a file system.
    • eForth has no idea of files or any other mass storage systems. Files and blocks are not ( part of ) eForth. eForth has not to deal with mass storage.
    • Instead, eForth implements serial I/O only. The source and destination of data must be a serial port.
    • An implemented serial port, as destionation of serial data, might catch the data and save the data in files, on a local file system.
    • eForth just processes a stream of text ( the traditional Unix shell & Tcl/Tk data processing idea ).
  • Experts told me, that eForth is not a “full Forth”, but a very limited minimal Forth.

FORTH-83 Reference Implementations by Henry Laxon & Mike Perry

Downloads
  • Forth Interest Group ( FIG ) "Public Domain Forths" - “3 Forth-83 standard implementations by Henry Laxon & Mike Perry” ( MSDOS, CP/M, CP/M 68K ).
    • The MSDOS & CP/M archives are ok :-).
    • The CP/M 68K archive is incomplete. Additionally, at least the “README.68” text file is corrupted and contains false bytes :-(.
  • Mirror of "ftp.mayn.de/" - Forth-83 68K - Incomplete distribution. Instead of “f83.68k”, there is a 1 byte large file “f83.68k.txt” :-(.
  • GitHub "uho / F83" - “F83 (Forth 83 Model implementation, 16Bit) by Henry Laxen and Mike Perry, 1984. 8080, 8086, and 68000 distributions”. Complete distributions, including binaries ( “F83.COM”, “F83.COM”, “F83.68K” ) :-).
Resources
  • While the MSDOS and CP/M implementations are shipped with executable applications ( “F83.COM” ) :-), the CP/M 68K implementation consists of some ”.BLK” files, i.e. no “F83.COM” file :-(.
  • A suitable CP/M emulator for Windows is Ronald Daleske's “EMUZ80 - Z80 / CP/M - Emulator” ⇒ See Embedded Systems.
    1. Download eth FORTH-83 archive “f83v2-80.arc”.
    2. Unpack the ”.ARC” archive.
      • The free archiver IZArc on Windows can unpack ”.ARC” files of the CP/M and CP/M68K implementations :-).
    3. Copy the implementation files to one of the subdirectories “CPM_LW_A” or “CPM_LW_B”.
    4. Start the emulator, at CP/M shell promt enter:
      1. “C:”.
      2. “F83”.

    • “calForth is a forth language interpreter and compiler. It... will run on most *nix environments. It also includes a debugger and tracer. It's coded in 'C' to allow easy modification. Also, support for the 8051 processor has been added”.
    • “It will run as a forth interperter, as well as strictly compile an executable”.
C-FORTH: a portable, C-coded figFORTH Interpreter, by Allan Pratt ( 1985 )
  • Mirror "ftp.uu.net/comp.sources.unix/volume1/cforth" - “C-FORTH: a portable, C-coded figFORTH interpreter” by Allan Pratt, 1985-04. Project description, but no source ( “part1.gz”, “part2.gz”, “part3.gz” ).
  • GitHub "pahihu / cforthu", 2020 - “C-FORTH by Allan Pratt”. “This is c-forth written by Allan Pratt containing modifications by John P. Nelson, Ken Brown and Marc de Groot”. “Limitations: cell addressed FORTH virtual machine”.
  • EDM/2 "C-Forth".
    • “An OS/2 port of Allan Pratt's portable Forth interpreter for DOS that featured a basic interpreted core written in C and the rest of the tool written in Forth. It is often known as Portable Forth especially on DOS and OS/2, but that name should be avoided since it name wise clashes with Portable Forth Environment. It is a fairly slow implementation and although the porter announced that he would add OS/2 specific features they never showed up so not a lot to recommend it over and above the original 1985 DOS version”.
    • “On the other hand, at 20k in total it is tiny and still offers the usual Forth interpreter functions like execution tracing, single-stepping through instructions, breakpoint detection and breakpoint stack dumping. It also has a couple of small neat touches that not all Forth implementations have such as saving and automatic restoration environment”.

      • Experts told me: “If what you are looking for is a Forth where the same code (both the Forth system code and your Forth “user code”) can be built and run on both the PC and on a dev board, then BoardForth may be an option for you”.
    2. GitHub "CCurl / CForth" - “A new Forth project”.
    3. GitHub "CCurl / Forth_C" - “Another Forth. This one creates a 'bare metal' Forth virtual machine. Written in C using Visual Studio”.
    4. GitHub "CCurl / Forth-GCC" - “This is a simple token-threaded (byte-code) implementation of Forth, written in C for GCC. Yes, I know ... ANOTHER Forth implementation. This one creates a 'bare metal' Forth virtual machine. The goal of this project is to create a basic, easy to understand, and easily extendable implementation of a Forth virtual machine. To that end, the virtual CPU has less than 50 instructions, which make up the VM's opcodes. They are also the Forth system's primitives”.
    5. GitHub "CCurl / Forth-PCode-Asm" - “Yet another Forth implementation. This one is a PCode based one written in assembler”.

FINF Is Not Forth
  • GitHub "lpereira / finf" - “FINF Is Not Forth. FINF is a simple implementation for a FORTH-like language for the Arduino platform... Current version weighs about 8kB of object code (8.8kB if built with TERMINAL defined), making it suitable even for less beefier Arduinos, such as the ones based on the Atmega168 microcontrollers (even though it runs out of memory quickly and starts to behave weirdly)”.

    • Narkive News Archive "comp.lang.forth.narkive.com", Thread "GraspForth ... a new forth written in C", 2004.
      • “You seem to have missed the whole point of my post. In respect to 'tethered' forth's for example. I don't want one. The reason is simple, I don't want to carry around the development system in the field. For example, I want to be able to configure/program/modify my products in the field with a PDA for example .. or a laptop .. or the kitchen sink, anything with a serial port. I don't want to drag around a development environment, if I wanted that I'd write using C tools”.
      • “and eForth cannot be ported with GCC (AS) AS cannot have look-ahead ORG statements. Of the Free Forth's eForth(or hForth) is the best assembly based solution *if* you have the commercial assembler for that micro .. and you have time for the port” :-(.
      • “As I read it, eforth even lets you generate a Forth for a target system using a different assembler, by only using its macros and ignoring its own code generation functionality. The idea then is to have the 30-ish pieces of machine code set up as bit patterns of data, with the rest of the high level Forth still provided as data as before. Of course, the time problem goes up, but it's a lot more practical than implementing a whole Forth for a virgin machine with no tools for it. Traditionally, of course, you would go the route of cross compiling from a different Forth platform”.
      • “Well, many Forths are me-too efforts. They feature the same basic engine, the same ANS-Forth vocabulary and they are used in the same way. There are a few that are different:
        • C-based FORTH:
          • OpenBios - doing Fcode.
          • FICL - the way it interfaces with C.
          • 4tH - conventional compiler instead of Forth engine.
          • I have seen a C-based Forth in 1K C-code (First??) some time ago in a dutch Forth magazine.
        • Not C-based FORTH:
          • RetroForth - very minimal, very versatile, very portable.
          • ForthCMP - makes tiny, very speedy standalone executables.

    • “Indirect-threaded code (ITC) Forth”.
    • “Unlike mecrisp – which could be considered muforth's main 'competition' – muforth supports a tethered development model, where the dictionary names and all the interactive command processing live on the host, and only the code and data live on the target machine. This makes it possible to target very small devices with a few kilobytes of flash. In contrast, mecrisp needs at least 16 KiB of flash to be useful; 32 KiB is a more comfortable minimum”.
    • “5.11. What is a tethered/umbilical Forth system? A tethered Forth system is a cross-development environment where the host and the target are connected at run-time (during development), allowing full interactive use of the target system without requiring all the space that a full-blown Forth system would require on the target. E.g., the headers can be kept completely in the host. Tethered systems may also provide the compilation speed and some of the conveniences of a full-blown Forth system on the host. Tethered systems are also called umbilical systems”.

StoneKnifeForth
  • GitHub "kragen / stoneknifeforth" - “This is StoneKnifeForth, a very simple language inspired by Forth. It is not expected to be useful; instead, its purpose is to show how simple a compiler can be. The compiler is a bit under two pages of code when the comments are removed. This package includes a 'metacircular compiler' which is written in StoneKnifeForth and compiles StoneKnifeForth to an x86 Linux ELF executable”.
Win32Forth ( for Windows )
  • The OpenSource ANS94 FORTH system SourceForge "The Home of the Win32Forth Project Group", SourceForge "Win32Forth"
    • Latest version is “Win32Forth 6.15.05” ( and Tom Zimmer's last Win32Forth Version 4.2 Build 671 ). At some other places, there might be a “WinForth 6.16”, though...
  • Not under active development since 2018 :-(.
  • The installer must be pointed to a directory, in which the installer then creates a “WIN2FORTH” directory. The directory “WIN2FORTH” must not exist :-), else the installer aborts with an error :-(.
  • Implementation size:
    • Startup screen: “2,812 Words in Application dictionary. 2,631 Words in System dictionary. 5,443 Words total in dictionaries. 20,312 Windows Constants available”.
    • “WORDS” displays 2447 of the 5448 words in the system.
  • List of FORTH words:

A simple installing complete IDE, with editor, full source debugger, with tracing capabilities, Assembler, Disassembler, Full C interface, lots of libraries for TCP-IP for example, is easy to write a server (in real it is already written).... Win32forth has lots of examples ready to go, how to access the full hardware of your PC, you can read and write on COM ports Parallel ports” :-).
  • Expert comment about the history of Win32Forth.
    • “Tom Zimmer hat Anfang der 2000 aufgegeben, aber er hatte viele Programmierer dabei zum helfen, die danach alleine oder zusammen weiterentwickelten”.
    • “Es waren ca 20 Top Programmierer in diesem Team, Howerd Oakford, Dirk Brühl und ein anderer Dirk”.
    • “Fast alle Forth Programmierer die Du heute kensst, haben mit Win32forth Programme geschrieben. es war ausserordentliches System”.
    • “Win32forth lauft fast kaum in modernen Rechner, so es macht kein Sinn. Win32forth konnte man nicht in Windows >XP installieren. so haben alle aufgegeben. Windows hat win32forth als ein Virus Programm gesehen, so kannst Du auch nicht mehr den Turnkey oder SAVE benutzen, es wird alles von der Festplatte gelöscht”
    • “Das tolle Feature von Win32forth war, dass Du EXE Programme herstellen konntest und danach verbreiten. Als Windows dies dichtmachte hat der ganze Prozess kein Wert mehr”.
    • “Es gab viele Seiten mit Win32forth Programme, es gab sogar Seiten mit Win32forth Server auf Forth geschrieben, die als Virus auftauchten und dann gesperrt wurden. Es fing eigentlich mit einem XP-Patch schon an”.
    • “Man hätte es retten können, aber es gab Leute die mit Win32forth Virus Applikationen schrieben. Computer Chaos Club usw.”.
  • Forth-Gesellschaft e.V. "Win32Forth heilen !", 2019-03-10 - “Trotzdem wird Win32F als 'Falsch Positiv' identifiziert und blockiert. Nach weiterer Suche fand ich einige Probleme im HEAD von PE-EXE. Einige Eingaben erwiesen sich als problematish, und mit einem anderen HEAD, geborgt aus einer aelteren Version von Tom Zimmer, konnte ich die Entdeckungsrate ganz beeindruckend vermindern”.
  • Fan pages & FORTH application pages.
Howerd Oakford's Win32Forth6v05H
  • Inventio Software Techie Page by Howerd Oakford - “Win32Forth6v05H 2019 Mar 02. The ‘H’ is for Howerd, although I have kept as much of the original V6.05 as possible. This version of Win32Forth runs under Windows 7 and 10 and does not trigger my anti-virus program”.
  • Experts told me, that “Win32Forth6v05” still is almost like the latest Tom Zimmer's last “Win32Forth Version 4.2 Build 671”! There was never a version 5. Some Win32Forth releases after 6.05, Win32Forth was heavily modified. The current stable version of Win32Forth is 6.15, in 2021, though there is a Win32Forth 6.16 somewhere out.

Win32FX based on Win32Forth 6.01
  • SourceForge "Win32FX". SourceForge "Win32FX", win32fx.sf.net - “Evolved from Win32Forth 6.01. Code runs ten times faster on older cpu's. Absolute addressing makes the VM simple to understand. Five stacks and demos showing why modern Forths need at least 4, and preferably 5 stacks to be viable in today's computer”.

  • Parallax Forums "PropForth V6?".
    • “PropForth5.5 is last version for P1”.
    • “I have been trying to use Tachyon for my project, but it is sufficiently unique and for me it is quite frustrating because it is different in its behavior from other Forth implementations. Peter Jakacki is a very talented programmer and he has developed this system to fit his way of thinking. I am struggling trying to figure stuff out. Things that were easy in other implementations are vague and hard to discover”.
  • Parallax Forums "How about a 'FORTH stamp'?".
    • There are at least 4 different versions of forth for the propeller. All versions can make use of the multiple cores of the propeller.
      • Three versions (Tachyon 3 & 4, and Propforth 5) are optimized for the propeller with many words defined for sensors, communications, actuators.
      • One version (pfth) is a standard ANS forth with some key words defined for use with the propeller. I found it useful for learning interactively some low level propeller features by interactively adjusting parameters in one core and transferring data to words running in other cores.

Using an OpenSource FORTH for commercial Projects to generate a Sales Product

  • Experts warned me to use a modern OpenSource FORTH ( like some FORTH for the ESP8266 ) for commercial embedded system projects, as some of these products are using several different OpenSource libraries ( e.g. to handle WiFi on the ESP8266,.. ) with often a handful of different OpenSource licenses, including some problematic licenses. The idea to compile this with a self-written application in FORTH language to a commercial saleable binary product, without that the hole commercial binary product is effected by the OpenSource libraries, is not quite realistic :-(.

History of FORTH

FIG's & TheFourceSource's History of FORTH

  • Forth Interest Group, Glen B. Haydon "LEVELS OF FORTH", TheFourceSource "The Forth Source - Catalog" ⇒ “Levels of Forth”, “Implementation Levels of Forth”.
    1. “Level 0”.
      • “On several occasions C.H. Moore has listed approximately 63 functions which he considers the essence of Forth”.
      • 45 functions noted by Glen B. Haydon at one presentation pf Charles Moore: 
        + - * /MOD MIN MAX = AND OR XOR NEGATE ABS NOT */ DUP DROP SWAP OVER DECIMAL HEX OCTAL . n .R CR EMIT KEY : ; CREATE , ALLOT IF ELSE THEN FOR NEXT I
      • Glen B. Haydon: “There are only 45 functions in this list. You can see about which period this was. The list does not include BEGIN, UNTIL, and several other functions belong in Level 0. A figure of about 63 is appropriate. Three functions are used for output to the display. He included no functions for any kind of storage. Screens are not included much less any means of writing on such a screen. Something more than Level 0 is necessary to provide anyone but Chuck enough to work with”.
    2. “Level 1”.
      • fig-Forth.
        • “There was little in the way of documentation beyond the Installation Manual and the source listings. The older publications such as the Kitt Peak Primer and Using Forth did not mesh well with the public domain version available” :-(.
          • “Kitt Peak Primer” ⇒ See FORTH 3/6.
          • Document “Using Forth” ???
        • “The fig-Forth implementations took over the disk precluding its use for other programs. The error messages were stored on a disk” :-(.
    3. “Level 2”
      • FORTH-79.
        • “79 Standard made about 40 changes to the functions in fig-Forth”.
        • “Soon there came the 79 Standard which made several changes. It was then proposed that the Forth Interest Group stop supplying the fig-Forth source listings” :-(.
        • Book by Leo Brody “Starting Forth”, 1st. edition.
      • MVP Forth, up to 240 or up to 500 functions. The MVP Forth implementation of FORTH-79 takes over a disk format. But the file on Gene Forth Round Table includes several added utilities which allow one to access screens in files and the compiling of text files written with any word processor.
        • “A Forth editor described in Chapter 3 of Starting Forth written by Sam Daniels is included”.
        • Suggested reading:
          • Document “MVP System Documentation”.
          • Document “MVP FORTH Guide”.
          • Book “Starting Forth”, 1st Edition by Leo Brodie.
          • Free document “The Forth Guide” by by Glen B. Haydon.
    4. “Level 3”.
      • FORTH-83, up to 1000 functions, including the 132 functions from the 83 Standard.
      • Document by Ting “Inside F83”.
    5. “Level 4”.
      • FPC Forth ( = F-PC Forth ), by Tom Zimmer. 2500 functions. Based on the 83 Standard. All of the source code is in text files.
      • Documents by Ting “F-PC Technical Reference Manual” and “F-PC Users Manual”.
    6. “Level 5”.
      • MVP-F32 Forth( = F32 Forth ), by Rick VanNorman. 32-bit FORTH, up to 900 functions.
    7. “Level 6”.
      • Norm ANS Forth, 1994.
      • THIS4TH Forth.
      • MVP-F32 ( = F32 Forth ) by Rick van Norman, with 32-bit MSDOS extender ( DPMI ) support.

Forth Family Tree and Timeline
Gforth's History of FORTH
  1. All early Forth systems were custom-made, usually by Charles Moore, who discovered (as he puts it) Forth during the late 60s. The first full Forth existed in 1971.
  2. The principal architect of microForth was Dean Sanderson. microForth was FORTH, Inc.'s first off-the-shelf product. It was developed in 1976 for the 1802, and subsequently implemented on the 8080, the 6800 and the Z80.
  3. A team led by Bill Ragsdale implemented fig-Forth on many processors in 1979. Robert Selzer and Bill Ragsdale developed the original implementation of fig-Forth for the 6502 based on microForth.
  4. VolksForth was written by Klaus Schleisiek, Bernd Pennemann, Georg Rehfeld and Dietrich Weineck for the C64 (called UltraForth there) in the mid-80s and ported to the Atari ST in 1986. It descends from fig-Forth.
  5. Bernd Paysan wrote bigFORTH, a descendent from TurboForth, an unreleased 32 bit native code version of VolksForth for the Atari ST, written mostly by Dietrich Weineck.
  6. Gforth descends from bigFORTH (1993) and fig-Forth. Of course, a significant part of the design of Gforth was prescribed by ANS Forth.
