This package contains all neccessary ANSI-C source files to build a running Forth-environment on most UNIX machines, on DOS and on OS/2. The Forth-system is closely modeled along the new American National Standard for the programming language Forth. I implemented every word of every word set mentioned in the dpANS-6 document of june 1993. Additionally it is compatible to Forth-83. WWW: http://pfe.sourceforge.net/
