Check out Lingua::31337 on CPAN. That C really does stand for comprehensive. It works the other way around, ie it converts normal text to 31337, but you coud probably reverse the conversions it uses. Best of all, it's written by the founder of this list (hi Casey!) but I don't think it has ever been plugged here. It's about time that was remedied. I'm sure Casey would be happy to accept a patch to add a 313372text function. -- Paul Johnson - [EMAIL PROTECTED] http://www.pjcj.net -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
