Re: $ARGV Help

RE: $ARGV

$ARGV[0] and $ARGV[1] are not file handles. They are elements of commandline argument array @ARGV. ARGV is a special file handle that holds the current file being read by an empty <> operator. $ARGV is another special variable that holds the name of the file currently being read by an empty <>
