Just a thought, using the prematch and postmatch at all will slow down all regular expressions as the engine will have to save them for every regex in your program.

After reading chapter 5 of japhy's book, you'll be able to rewrite prematch as: `substr($string, 0, $-[0])` [download] For example: `#!/usr/bin/perl -wT use strict; while (<DATA>) { chomp; $_ = substr($_, 0, $-[0]) if /#/; print "$_\n" if $_; } __DATA__ ### Hello 99:88:77 100:11# This is a comment abc:def ### Comments also 999` [download] -Blake	[reply] [d/l] [select]
