um, your prob is right here!
ld (CURSOR_COL),a
is what it should be!

Then after you press up, it was supposed to add 1000 to it, and subtract 1000 if you press down.  However, what it really does is display 1*10^19 and displays some strange numbers, like 285 and a lot of zeros or something like that.  What's going wrong?!?!
