in reply to Extracting code into a subroutine

First write differences down. Then design subroutine arguments. Then desing subroutine. What are the differences?
  • List of field indexes.
  • grep regexp (NETPACKET, NETERROR)
  • grep regexp (Network, Busy, Memory)
  • what to do with arguments?
  • others?
Then subroutine arguments:
sub yoursub { my ($rangearrayref, $firstre, $secondre, $subref) = @_; ... } yoursub([2..7], 'NETPACKET', 'Network', \&transformNetpacketSub);
or hash style:
sub yoursub { my %args = @_; my ($rangearrayref, $firstre, $secondre, $subref) = ($args{-range}, +$args{-firstre}, $args{-secondre}, $args{-transformsub}); ... } yoursub(-range => [2..7], -firstre=>'NETPACKET', -secondre=>'Network', + ->transformsub=>\&transformNetpacketSub);
And then the only problem is to write proper transformNetpacketSub. I would do it like this:
sub transformNetpacketSub { my $str = shift; # do anything with string return $str; }

    Thanks to all who responded. It definitely gave me some ideas on how to proceed, which was all I needed.

Lady_Aleena ponders a meditation of her own, but it would be on a far far less important topic.
[marioroy]: I'm hoping to have a release in about a week's time.

marioroy MCE isn't important by any means. Just wanted to complete this task. Hobo needed more love and MCE::Shared as well. It wasn't easy at all.
