Hash of Hashes, Hash of Arrays and Hashes

[eWish]

I am in need of a good tutorial that explains taking the keys of one hash and the elements in a HOA and making them a HOH. I have a file that has is pipe delimited with 374 fields per line and 7.500 plus lines per file. I have about five of these files. I need to get this into a database and did not want to do it manually, Preserving the order is crucial. I am using Tie::Hash::Indexed to keep the order.

Basically, $HOH{$key_of_HOA}->{$key_of_hash} = $element_from_HOA;

I have tried using nested for loops without success.

Any suggestions?

Don't know if you have seen this one yet, but here is one of my go-to pages for hash of <anything>.

Hope it helps!

Here is what I ended up doing.

foreach my $id (keys %listings) {
     my $count = 0;
        foreach my $field (keys %fields) {
            $count++;
            $data_hash{$id}->{$field} = $listings{$id}[$count-1];
 
        }
 
}
