| P F E | The Portable Forth Environment |
|
The Portable Forth Environment (PFE) is based on the ANSI Standard for Forth. The PFE has been created by Dirk-Uwe Zoller and had been maintained up to the 0.9.x versions (1993-1995). Tektronix has adopted the PFE package in 1998 and made a number of extensions. It is now fully multithreaded and it features a module system. You can load additional C objects at runtime to extend the Forth dictionary. It is best targeted for embedded environments since you can easily exchange the terminal driver and the initilization routines. |

DocumentationThe standard documentation is automatically generated and benefits from comments directly integrated in the PFE sources. See the unpacked documentation on this site, and fetch a copy of the compressed archive from the snapshot ftp directory . In any case, you should read some documentation that encompasses the ANSI Forth Standard, e.g. the Draft Proposal for ANS Forth There are also a lot of documents to be found at the WWW, the Forth Programming Webring at ZForth is a good starting point.

Guido Draheim has been working on PFE at Tektronix in the last years. The released version is now maintained by me, Guido Draheim on a sparetime basis. You can contact me by e-mail, <guidod@gmx.de>
In 1998 I had been contacting the original author Dirk-Uwe Zoller - well, his e-mail adress had changed since 1995 but I did find him. He told me that he has no serious intentions at all to do anything about Forth again, but he likes to look for his old project PFE on an occasional basis. He has put up a new homepage lately under www.dirk-zoller.de.
