    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!

[Corion]: marto: Yeah - their mother picked all three of them up at the kindergarden to then go to the hospital, and all three of them were well behaved, and all also were quite obedient when they came home, so they recognized the situation
[Corion]: Nice to see that the kids have some understanding of important things that happen and the appropriate behaviour :)
[marto]: at times mine surprise me with this behavior :)
[Corion]: I mean, in a way it would be nicer+easier if they always where that obedient, but it's comforting to see that they are when it matters, at least for now ;)
