pForth - Portable Forth in 'C'

Translations to Français by Antoine Billiau, or Chinese by Letoh

PForth is a public domain, portable ANS Forth based on a kernel written in ANSI 'C'. This makes it easy to port pForth to multiple platforms. So far, pForth has run on Macs, PCs, SUNs, Amigas, Linux, BeOS, Nokia Communicator, SGI Indys, 3DO ARM systems, 3DO PowerPC systems, WebTV systems, Hitachi SH4, OpenTV prototypes, Compaq Ipaq 3970, Sharp LH79520 ARM processor, Ciena Systems networking hardware, and some internal projects at Lucent. If you build pForth for an embedded system, please let me know and I will add your machine to the list of machines that pForth has run on.

7/20/08 PForth source has been put on Google Code so we can collaborate easier.

Latest update: V23 on 7/20/08 as a Google Code project

PForth was developed by Phil Burk. Phil Burk is available as a contractor for pForth classes, application development, or porting pForth to new platforms.

PForth is provided free of charge to the Forth community. But if you are using pForth for commercial purposes, then you may wish to support the future development of pForth by making a donation of any amount by credit card.

PForth Features

ANS standard support for Core, Core Extensions, File-Access, Floating-Point, Locals, Programming-Tools, Strings word sets.
Compiles from simple ANSI 'C' code with no special pre-processing needed. Also compiles under C++.
INCLUDE reads source from normal files, not BLOCKs.
Precompiled dictionaries can be saved and reloaded.
Custom 'C' code can be easily linked with pForth.
Handy words like ANEW INCLUDE? SEE WORDS.LIKE FILE?
Single Step Debugger
Smart conditionals. 10 0 DO I . LOOP works in outer interpreter.
Conditional compilation. [IF] [ELSE] [THEN]
Local variables using { }
'C' like structure defining words.
Vectored execution using DEFER
Can be compiled without any stdlib calls for embedded systems. Only needs custom KEY and EMIT equivalents in 'C'.
