If there is a better way , please enlighten me. no, you are missing the point. the loop variable needs a name. all loop variables are reused, hence the need of a loop!! but what kind of value is stored there in $_? we can't tell quickly without analyzing the loop code and seeing where the data comes from. whereas with a properly named loop variable, we know what it is all the time inside the loop. uri -- Uri Guttman ------ u...@stemsystems.com -------- http://www.sysarch.com -- ----- Perl Code Review , Architecture, Development, Training, Support ------ --------- Gourmet Hot Cocoa Mix ---- http://bestfriendscocoa.com --------- -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
