Hello Anonymous,

Although that the other monks have already answered your question I would like to add something. Why not to use ARRAYS OF HASHES?

Sample of code provided under:

#!/usr/bin/perl
use strict;
use warnings;
use Data::Dumper;

my @data1 = (
{
    'NAME' => 'PAUL DY',
    'DATE' => '2009-05-05',
    'NUMBER' => '00001',
},
{
    'NAME' => 'ANTHONY RD',
    'DATE' => '2012-01-07',
    'NUMBER' => '00003',
}
    );

print Dumper \@data1;

=data1

$VAR1 = [
          {
            'NUMBER' => '00001',
            'NAME' => 'PAUL DY',
            'DATE' => '2009-05-05'
          },
          {
            'DATE' => '2012-01-07',
            'NUMBER' => '00003',
            'NAME' => 'ANTHONY RD'
          }
        ];

=cut

my @data2 = (
{
    'CAR1' => '1',
    'CAR2'  => '2',
    'CAR3' => '3',
},
{
    'CAR1' => '1b',
    'CAR2'  => '2b',
    'CAR3' => '3b',
}
    );

print Dumper \@data2;

=data2

$VAR1 = [
          {
            'CAR3' => '3',
            'CAR1' => '1',
            'CAR2' => '2'
          },
          {
            'CAR3' => '3b',
            'CAR1' => '1b',
            'CAR2' => '2b'
          }
        ];

=cut

push my @AoH , ( @data1 , @data2 );

=alternatively

my @AoH = ( @data1 , @data2 );

=cut

print Dumper \@AoH;

$VAR1 = [
          {
            'NUMBER' => '00001',
            'DATE' => '2009-05-05',
            'NAME' => 'PAUL DY'
          },
          {
            'NUMBER' => '00003',
            'NAME' => 'ANTHONY RD',
            'DATE' => '2012-01-07'
          },
          {
            'CAR3' => '3',
            'CAR2' => '2',
            'CAR1' => '1'
          },
          {
            'CAR1' => '1b',
            'CAR2' => '2b',
            'CAR3' => '3b'
          }
        ];

There are many ways to play around with these just try.

For example you can Making References with array of hashes.

Sample of code:

my $refAoH = \@AoH;

print Dumper $refAoH;

Same result as above.

Hope this helps.
