I apologize for not being clearer. I have a DR> three-column file that describes a bunch of parameters: it is always important to be clear in problem specifications. your numbers in the example were just row numbers which didn't mean anything.

I'll give File::Slurp a try with DR> some benchmarking. you need to specify where and how those numbers are brought into this program. if they are an array of values you can do it one way. if they are derived based on other data in the row you can do another. not knowing means i can't improve it for you. 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/
