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.

      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 (==, !=, <, >, <=, >=, <=>).
