>This will fail in several different ways - some forms will get skipped over, and you'll iterate beyond the end of the list. If you use this logic, iterate downwards from _SCREEN.FORMCOUNT rather than up.

On top of that, is

FOR i = _SCREEN.FORMCOUNT

even valid? I usually have a TO clause in there, but this may be one of those funky shortcuts. Maybe, he meant to say

FOR i = _SCREEN.FORMCOUNT TO 1 STEP -1

And was right, but still wrong (just forgot the rest?).
