Dang, sorry about that last post, pressed the button too early!

Anyway, Jules, I see your point. I know about the difference between
'c' and "c", but I didn't understand that it would make a difference
when my code problem arised. I see it now, though. In my example,
the FIND searches for a "c" (sequence format), but tries to match that
with each induvidual ATOM in zALPHA - which of course doesn't match.
(Hope I got it right, and didn't make an ass of myself. :))

Again, thanks to you and all for their feed backs.

Regards, Ken aka ZNorQ.
