The input is just like this way:

ld	hl,_X_coord
push	hl
ld	hl,_Y_coord
push	hl
call	fill

So you need to grab the value from the stack (it's the Small C way, I
know), and 'calculate' with those values...

Oh, and (0,0) is top-left, you should know I think...

Nothing more to say...
(I could send you the source I currently have, might be some help if you
want to give it a try)
