For a lot of info on Forth go to:
Getting up on a soap box now....
FWIW, I know that Forth is still used in a number of embedded systems
by a small (and diminishing) community. I've always thought that if
you can get over the learning curve, Forth offers things that other
development systems (it's more than just a compiler) only aspire to:
great interactive debugging capabilities, quick modelling,
portability, quick hardware interfacing. And more.
There have been a couple of stabs at Forth for the PICmicros, but the
architecture is one of the few micros that is quite Forth un-friendly.
The next PICmicro architecture, the 18Cxxx, will have an addressable
hardware stack, incrementing/decrementing pointers to program memory
and file register space, linear file register space, and some other
handy features that will make it easy to implement a very efficient
Forth nucleus on-chip ('though that's not the reason the features
Unfortunately, with the waning interest in Forth, there might be no
one who's interested enough to do it.
