Matthias, Marcin,
thanks a lot for the infos - I've spent a time to work in order to
write my first amforth routine ++_ - based on Lubos sources so I've

Basically my problem is not the assembler of any processor, but what

nested comments are not allowed. I just tried
your code with gforth (0.7.0) and it produces
(other but) similiar strange output.

Thats sad. I know of no s(usable) imulator for the avr's. The Atmel
Development studio has a built-in simulator, but I never managed to get
amforth running there. It simply crashes.

Hi, I can imagine the headache, indeed. The experts may answer the
simulator Q.. I've put the stuff into AVR Studio 4.18 SP2 (build 700
and 692)and I've tried to run amforth in simulator. IT WORKS,
however after few steps the AVR Studio crashed (it shots down the
simulator) - always on first "ijmp"

hi, all
I've got headache on debug the words on the board. I need a simulator for
amforth.
Does anyone know how to solve it? Or how to compile the amForth to X86? Where
are the forth source of the core?
Thnks and Best Regards.
