Brian is right, of course.

Here's how I do it:

    if ($#ARGV < 0) {
        eval "use Mac::StandardFile";
        $file = StandardGetFile('', 'TEXT');
        if ($file->sfGood()) {
            push(@ARGV, $file->sfFile());
        } else {
          exit(1);
        }
    }

Please note that the eval() isn't strictly necessary.  I use it for 
cross-platform compatibility reasons. If you have no reason to suppress 
evaluation until runtime, pull it. Once again this is straight from MPPE, 
Chapter 8, page 124.
