HELP!!! I need to figure out how to switch between the main and alternate video buffers of an SE, and I need some sample code as to how to do it. The only reference to this process in IM is on page 20 in IM-III. Unfortunately, it assumes I know a lot more than I do, and I am very frustrated. I don't completely understand VBLTasks, let alone how to clear bits of a data register. I am using LightSpeed Pascal (v. 2.03), on a Macintosh SE with 2.5 Meg, and I am trying to display images on a 19" monitor (Laserview) within 1 screen refresh (which is seeming more and more impossible with each passing day). ANY help would be greatly appreciated. Maria I.
