Hi pito,
Thanks for the stack printing words.
I suggest to have the tos at the right or bottom end, for
two reasons:
- In case there are many values on the stack, having the tos
at the end avoids scrolling the "top" value off the
visible screen.
- Having the tos at the right is consistent w
.. and my not so elegant code, it works as well and is commented a
little bit. Good for beginners who are not reading forth's sources..
Thanks a lot Marcin, your code is of course optimised to the
bones..Pito

Marcin, yes to study the manual is important! However, we do not do
it quite often..
I've seen the manual and therefore I am using register allowed.
loadtos and savetos works with 24 and 25(? as used in loadtos,
savetos), and I used 10-13 and 14-21 for ++_ routine. However
results differs. So my un

Marcin, I am ansewering to you in this thread: No, R16 and R17 are
ok for my cpu, but not correct from OS prospecive. I've spent a
sleepless night with playing with registers against definitions in
macros.asm (it seems Registers 10,11,12,13, are not used by OS but
in reality code crashes) and the p
