Thank you very much Count Zero for prompt. Really appreciate the help. the code works great... I have used it in reg ex actually because my perl set up does not recongize Modern::Perl line. downloaded from CPAN , but then install was complaining on other modules missing (Build, Metadata....) . downloaded all of them, did install but still the install on Modern package complains. is there a single place where I can install the whole package? thanks Natasa
