$var !~ /\D/ is preferred to $var =~ /^\d+$/ because: 1. The latter matches "123\n", which contains a non-digit 2. The former is faster, as it can stop looking when it finds a non-digit My mistake for suggesting the latter. Use the former. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
