Respected Monks,

Thank you very much for your replies. Some I am able to understand, some I need to re-read to understand because I am not very well versed with Perl, but I am amazed by the helpful nature of you all. Thank you very much. You all are absolute masters of Perl (and many other languages I guess). At 41 years, I hope in future years I am able to achieve even 20% of your level of mastery.
