how MS windows r Develop? which language is used

Perl is a name, not an acronym. Various backronyms have been created such as Practical Extraction and Reporting Language and Pathetically Eclectic Rubbish Lister, but they are not where Perl got its name. See http://perldoc.perl.org/perlfaq1.html#What%27s-the-difference-between-%22perl%22-and-%22Perl%22%3f for confirmation.
