The reason this has not been built into the language is that there would be an overhead associated with each loop to maintain this variable. The Perl5 team felt that this was not acceptable given that most loops do not need this information and, and you have noted, it's trivial to do the work yourself if necessary, if not always terribly elegant. -- 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>
