%final_data = @loop_data;

What is this line supposed to do?

Please also explain how you intend to use the data stored in %final_data.

Maybe you wanted to use the following construct instead?

return { names => \@loop_data };

The line `%final_data = @loop_data` will take the array and map the elements: `my @a = ('H','e','l','o'); my %fus = @a;` [download] so you will get `%fus: H -> e, l -> o` [download] In case you assign an odd list to `%final_data` the code will break! What about crating and array of hashes? and return the reference to the array?	[reply] [d/l] [select]

Need to store the data in a hash to return from the sub, if Dumper: `$VAR1 = { 'names' => 'mary', 'names' => 'john', 'names' => 'Doe', 'names => '' };` [download]	[reply] [d/l]

That's not how hashes work. A key can only appear once in a hash.	[reply]

Hi, this won't work as you use the same keys. `$VAR1 = { 'names' => 'mary', 'names' => 'john', 'names' => 'Doe', 'names => '' };` [download] Better try to make an array of hashes which would look like this: `$VAR1 = [ { 'names' => 'mary'}, { 'names' => 'john'}, { 'names' => 'Doe'}, { 'names => ''} ];` [download] or `$VAR1 = { 'names' => ['mary','john','Doe','']}; ];` [download]	[reply] [d/l] [select]

I know, wish it could be return as: `$VAR1 = { 'names' => 'mary'}, { 'names' => 'john'}, { 'names' => 'Doe'}, { 'names => ''} ;` [download] }, {	[reply] [d/l]
