----------------------------------- Mark, How did you get the machine to scroll from a non-512 byte boundary? In the past, when I changed the address of the logical screen I had to make sure that I placed it on a 512 byte boundary. When I did not I got a really screwy screen if I did not crash. How did you get around that? ---------------------------------------------------------------------------- John Joubert | /\ | /\ | _ jpdres13@usl-pc.USL or ... | \|<>|>|> \|<>|>|><`|`| ut-sally!usl!usl-pc!jpdres13 |-----/|-------/|---------------------- GEnie: J.JOUBERT | \/ \/ -----------------------------------------------------------------------------
