Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I want a more efficient way of referencing and loading data into an array without using multiple array variables(a,b,c etc..) Is that called a multidimensional array? 
while($num<10) {
    $num++;
    $data1="some random data from source 1";
    $data2="some random data from source 1";
    $data3="some random data from source 1";

    $a($num)=$data1;
    $b($num)=$data2;
    $c($num)=$data3;
}

Re: How do I use/reference Multidimensional hashed arrays?

    Here is how you create and use a multidimensional hash that contains arrays. 
    my $data_source = {};

for( my $i = 0; $i < 10; $i++) {
   $data_source->{a}[$i] = "source a's data";
   $data_source->{b}[$i] = "source b's data";
   $data_source->{c}[$i] = "source c's data";
}

    push, pop, splice, shift, unshifting is a bit ugly, but works too. 
    my $data_source = {};

for( my $i = 0; $i < 10; $i++) {
   push @{$data_source->{a}}, "source a's data";
   push @{$data_source->{b}}, "source b's data";
   push @{$data_source->{c}}, "source c's data";
}
