I am using a CGA adaptor. I am creating windows using an array which is in an absolute memory location ($b800:0000). When using the move command (move (videomem,othermemory,4000)) the screen 'snows'. How can I get rid or avoid this disturbing syndrom? Thanks in advance... SERAN@VMS.HUJI.AC.IL ..... Eran
