Don't use a regex. Use Date::Manip or Date::Calc. ------ We are the carpenters and bricklayers of the Information Age. Don't go borrowing trouble.

You aren't specific if these dates are stored individually in variables or part of a larger string. Here is a pretty generic solution: `s\|(../../)(..)\|${1}20${2}\|;` [download] You may need to be more specific like replacing the .(dots) with digit metacharacters. Good luck.	[reply] [d/l]

Thank you all for replying so quickly... I apologize for not supplying what I had tried; I haven't been thinking too clearly as I am finishing the last month of my paramedic school and my mind quickly turning to mush :\| I will play around with the ideas here this afternoon... Thank you again, Eric	[reply]

This one looks for the position and substitutes with a 20. Hope this helps. `my $date = '02/04/03'; $date =~ s#(?<=/)(?=\d{2}$)#20#; print "$date\n";` [download]	[reply] [d/l]

`s{(\d+)/(\d+)/(\d+)}{$1/$2/20$3} unless m{\d+/\d+/20\d+}` ---- I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident. -- Schemer Note: All code is untested, unless otherwise stated	[reply] [d/l]
