    Thanks. I think I see where you are going with this, but the array is coming up empty. I'll try and go over it again, regex's make my head hurt. :(

      Indeed. I conflated two similar techniques: getting a list of matches from /(...)/g and getting a list of matches from /(...)(...)(...)/. You don't get a list of matches from /(...)*/ (nor from /(...)*/g).

      What I should have written was:

      my @chunks = $description =~ /\G((?:[^\n]*\n){14}|.+)/gs;

      (tested even; works even)

      Update: Changed last * to + to eliminate extra empty string in result that I just noticed which is due to "quirk" in Perl regex processing (something I think we should just 'fix', but that is a story for another node, one I've written at least once already).

      - tye        

        Thank you very much! That works great!
