Just wondering too ... however, it might be interesting how things are
done on a 6800 compared to a 6809.
I'm constantly using a FIG Forth variant, eForth embedded in a 6809 SBC
It is direct threaded, the code field is executed, IP is in U, parameter
stack uses S and the return stack Y.
NEXT is inline, just a single command: PULU PC
Nice stuff to play around with ... or just to simply track the elegance
of Forth on the 6809. ;)
