They should. $m has an undef value when the loop starts, which will evaluate to 0 in numerical context. When the $m++ operation happens, $m becomes one. Thus, the final loop will occur when $m has a value of 79, but it will be the 80th iteration. Or did you notice something else that I didn't?

This could be used in check printing software, etc. (Not that I'm offering a solution, just pointing out these may not be the same). -Mark -----Original Message----- From: Glenn Meyer [mailto:[EMAIL PROTECTED]] Sent: Tuesday, April 09, 2002 9:26 PM To: Beginners" <[EMAIL PROTECTED]>"@glennmeyer.com Subject: Re: shrinking code Please, tell me what your are doing here. I have seen similar short code before but have no idea how to read it or why it works. Can you point me to docs or a boox the would help? Thanks!
