    What I do to make sure data is going to be in the vars that come in I usually use:
    if (! $myvalue ){ $myvalue = $defaultValue; }
    If this is what you are asking.

      Another way to write this is:
      $myvalue ||= $defaultValue;
      ...of course, if $myvalue had a "0" as a legitgimate value, you would want something like:
      defined $myvalue or $myvalue=$defaultValue;
