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.
