Correction to Bob's Fast Screen Scroll............Jim Church

If you tried the fast scroll from Bob Sander-Cederlof's article "Some Fast Screen Tricks" from the September issue, you might have been surprised.  Bob goofed!

He copied characters from line 16 into line 15 before moving line 15 to 14; ditto with lines 8, 7, and 6.  This in spite of his special attempt to save lines on the stack.  The problem is that he ran the loop backwards from 119 to 0.  If you change it to run from 0 up to 119, the scroll works correctly.

Change lines 1410, 1620, and 1630, and add line 1625:

Bob, you are going to get a lot of mail (unless they are asleep)!
