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.

Latest update: V21 released 9/16/98 for PC/Linux/Mac.

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.
