in reply to $ARGV dilemma

UPDATE: Err, I answered my own question right after submission; I apologize for asking such a silly question, and jumping to ask, before giving it any thought.
The solution is, of course, to just use unless $ARGV[2].

UPDATE 2: I guess I should have been more precise in both my question and update. Originally, the last argument was 0; but changing it to a string was the solution I came up with..

      unless $ARGV[2] works until someone passes a zero. You could amend it to   unless defined $ARGV[2] though   if 3 > @ARGV reads better, at least in my opinion.

    That won't always work.

    What if @ARGV = ("0","0","0"). Then $ARGV[2] is false and you get an error despite having three arguments.

    You probably like something like unless @ARGV == 3.
