You've got $i which seems to want to count up to $argc, but that's also the same as counting up to scalar @ARGV. Except that you iterate over @ARGV directly. And then you don't use $parm. Very confusing code. And I oughta know... I've been in front of Perl beginners for more than a decade now. You’ve got $argc which seems to be the same as scalar @ARGV.
