in reply to help with references

Both times that the loop is run, \@a returns a reference to the same array, because it is the same array that's on the right of the \ character.

To avoid that, you can use $h{$i} = [@a] instead, which copies the array and returns a reference to the copy.

    Thanks for the reply, moritz! using your method i'm no longer getting a ref of @a, but now i get refs of the individual arrays instead. it still won't work because if i change the AoA in $h{"1"}, the AoA in $h{"2"} will also be modified.

          '1' => [
                   [

                     1,
                     1,
                     1
                   ],
                   [
                     'a2',
                     2,
                     2,

                   ]
                 ],
          '2' => [
                   $VAR1->{'1'}[0],
                   $VAR1->{'1'}[1]
                 ]
