I am trying to make a program that uses the far most column and bottom row. (the ones that basic can't use)
Here's what I have, and I have no clue why it isn't working. Help please?
BCALL ClrLCDFull BCALL RunIndicOff Set fullScrnDraw,(IY+apiFlg4) LD BC,0 ;bottom left corner LD DE,95*256+63 ;top right corner BCALL DarkLine BCALL GetKey ;I get the same result even if I leave this off Ret
Oh, and I'm using Mimas .3 on my calculator.
What (I think) this code should do is draw a line from the bottom left corner to the top right corner, including the pixels at the corners.
What I am getting is a line across the screen, but neither of the corner pixels are darkening.
So I am getting the line I want, it's just that it is clipping the parts of it that are in the "forbidden rows".
This is just one of several tests I have done, all with the same results.
