Hmm... All right, so it looks like looks_like_number() is better. Usually when I read this forum or ask something, I always learn something and then something extra on top of that. In this case, I learned how to capture warnings, how to turn off warnings. (And don't laugh, my assumption was that you can't just create a block { ... } without having a "for" or "sub" or an "if" keyword in front of it. In other programming languages, you get an error if you just create a block with no keyword in front of it. In perl, this is allowed, and it is something that I just discovered. Lol)

Thank you for your informative answers!!!
