in reply to xs modifying passed value

print "It's $t\n" if $passfail eq 1;

Maybe a minor point, but "eq" is a string comparison operator, not a numeric comparison operator.

A Monk aims to give answers to those who have none, and to learn from those who know more.

      I always get em backwards

      Easy: If you want to compare characters (strings, char* or char[] if you know C), use the operators made from characters (eq, ne, lt, gt, le, ge, cmp). If you want to compare numbers like in mathematics, use the operators you know from mathematics (==, !=, <, >, <=, >=, <=>).


      Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)
        Excellent way to remember it ...

        Thank you!
