...sorry for the repetition.
There's no need to be sorry. I like to see a few versions of a solution. I often pick up handy techniques comparing different approaches.

A minor nit though, your snippet won't compile throws a warning under strict and warnings. This is a bit better.

#!/usr/bin/perl use warnings; use strict; use Data::Dumper; my @arr1 = qw{one two three}; my @arr2 = qw{four five six}; my @mainarr; push @mainarr, \@arr1, \@arr2; #print Dumper @mainarr->[1]; # <- line 12 #Using an array as a reference is deprecated at C:\perm\ line 1 +2. #C:\perm\ syntax OK print Dumper $mainarr[1]; __DATA__ $VAR1 = [ 'four', 'five', 'six' ];

My motto: "Test it _before_ you post it." :-)

update: it does compile ("syntax OK") but it throws a warning
