Would some kind and patient soul enlighten me as to the preferred method for fast access to text (character + attribute) screens. I'm sure this has been discussed ad nauseam, but I couldn't get reliable list service for nearly a year :-( I'm in the process of porting from BCC, and there is a just perceptible latency in painting the screen with menus when, using assembler routines and direct access to video memory, they used to flash up apparently instantly. -- Steve Blinkhorn <steve AT prd DOT co DOT uk>
