0086 9E11 ld (curcol),h
Zbasprgm.Z80 line 0086: unrecognized argument. ((curcol),h)
0087 9E11 ld (currow),l
Zbasprgm.Z80 line 0087: unrecognized argument. ((currow),l)
Thats what TASM kepps tellin me whats the problem?
"currow" and "curcol" are equated in "ti83plus.inc" so why does this happen? |

Just do
ld (currow), hl
That will store L in CurRow and H in CurCol because CurCol is just after CurRow in the RAM, and the processor first stores L, and then H.
In fact, you are not allowed to do what you tried to do. However, you can do something like
ld a, h
ld (curcol), a
But then, there is no utility to use HL.
I'm not sure of what I said, but it is something like this. Make several tests, you'll find it from yourself  |

| I don't know. mabey a space after the comma? Just use Tyraniek's way, because it is faster, and takes less code, as long as you understand it. Kind of like 'XOR A' instead of 'LD A, 0' |
