OK, it seems that I've taken "written in forth itself" too literally
:-).

Yes, I'm still trying to get a grip of Forth in general, and amforth in
particuliar (I've only used forth for a university class several years
ago, and am mostly a Scheme hacker these days).

Nice! I'm playing with the idea of using amforth on an ATmega8. With
just 8K of RAM, it might make sense to move the compiler onto the PC,
and just have the inner interpreter on the microcontroller -- or is that
just crazytalk?
