Portable Forth Environment <language> (PFE) A highly {portable} {Forth} development system based on the {ANSI} standard for Forth, by Dirk-Uwe Zoller of FHT, Mannheim, Germany. PFE aims to be correct, complete, usable, and simple but it isn't optimised for speed. It supports all {dpANS} {word sets}. It runs on {Linux}, {RS/6000}, and {HP-UX}. {Tektronix} adopted PFE in 1998 and added {modules} and {multithreading}. You can load additional {C} objects at {run time} to extend the Forth {dictionary}. It can be targeted at different embedded environments by changing the terminal driver and initilisation routines. Latest version: 0.30.27 preview, as of 2000-11-23. (http://pfe.sourceforge.net/). E-mail: Guido Draheim <[email protected]>. (2000-12-07)
