I'm new in perl although i'm an experienced programmer on the c language and its successors. I learned that perl borrowed some concepts in C so i bothered learning it. i'm trying to solve this palindrome thing. In C we have the isalpha() function which PERL doesn't have. Is there an alternative code on how to detect if a value is a character or not? besides comparing it from A-Z of course.

The short answer is no. Perl has no builtin function that checks if a character is an alpha character.
