Hello, Given you have this string: $str = "a9d0"; you can check if the 2nd character is a number or not by: my $c = substr($str,1,1); print $c=~/[0-9]/ ? "a number" : "not a number"; -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
