Forth has been a recognized programming language since the 1970's. ColorForth is a redesign of this classic language for the 21st century. It also draws upon a 20-year evolution of minimal instruction-set microprocessors. Now implemented on modern PCs, it runs stand-alone without an operating system. Applications are recompiled from source with a simple optimizing compiler.

re: This stuff is fascinating - is there anywhere we can download such stuff to play with? (or is it expensive proprietary code)
I suppose some of it is proprietary. A lot was based on concepts from taken from PolyForth circa 1980 and I'm sure I still use some of their code in the assemblers, etc. although I switched most of it over to fig-Forth over the years as it remained alive (still is). The multiuser/multitasking code was developed for a company long since buried by time but given the number of lawyers around today I am loath to openly distribute the sources.
To play cheaply, just look for any of the freely distributed versions and start with the most elementary versions. I have seen several that run as applications under Windows or OS/2 and I'm sure there must be a Linux port somewhere. You might also contact the Forth Intrest Group (FIG) if you can locate an address. Also check your news server under comp.lang.forth although they tend to be pretty much beyond a beginner.
