You can download here release 5.2 of a
32-bit ISO console Forth for MS-Windows
This is one of the Forth's that can be generated by the ciforth generic system at github:
ciforth, computer intelligence Forth.
The archive has a binary download, ready to run,
with documentation ready to be viewed or printed.
It is dll-based (as opposed to dpmi-based) with long filenames and access to DLL libraries. You can make executables that uses DLL's that are opened on a (different) target system. hence in principle to all facilities of MS-Windows. The built-in commands however only use kernel32.dll.
The 64 bit version of this Forth is available as a beta release. It passes the internal regression test and the Hayes test, but there may be problems with KEY and KEY?. The github archive for ciforth may contain a stable 64 bit release.
The last release 4 version is still available, as there still may be some programs on this website that require this version. . Version 4.0.7 will be the last release for DPMI : DOS protected mode interface. Simply unzip this file in a separate directory and start wina.com preferably from the DOS prompt. At last this is an official release and you can file bug reports against it. This is a dead link now, because Simtel shut down. A very old snapshot (beta) version is also available.
Do .SIGNON once you are in Forth, to find out what version you have. Go to the home page of Albert van der Horst
