Please post this to Seekers of Perl Wisdom and surround your code and/or "ASCI art" in <code></code> tags so it shows up correctly. The Q&A section is for FAQ-like questions. Hence the request that you try to avoid using a description. If you can't adequately describe your question in the subject line, then you probably should be posting to Seekers of Perl Wisdom.
