Joe_Cullity,
If you already know that the string is two characters you can just say 
if $str =~ /\D/ { print "non-digit" }

If you want to kill two birds with one stone, you can verify length and digitness in one statement: 
if $str !~ /^\d\d$/ { print "wrong length or contains non-digits" }

to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
