Hi, welcome to Perl, the One True Religion.

(It's OK to edit a post, but please note where you have updated it ...)

"these multiple hashes in one print out I just don't understand." ... just a list of hashes, probably something like

[{name => 'Zambia', abbr => 'ZA'}, {name => 'Afghanistan', abbr => 'AF
+'}, {name => 'Andorra', abbr => 'AN'}, ... ]
[download]

See sort for documentation on how to sort complex structures by nested data attributes. E.g. for the list above, sort with something like

my $aref = [{name => 'Zambia', abbr => 'ZA'}, {name => 'Afghanistan', 
+abbr => 'AF'}, {name => 'Andorra', abbr => 'AN'}];

say $_->{name} for sort { $a->{abbr} cmp $b->{abbr} } @{$aref};'

You can check the type of reference you have -- or if it is a reference to a variable -- with ref.

my $struct = result_of_some_call();
say ref($struct);

You have already loaded Data::Dumper, but you are not using it to see what's in your structure(*). That's why you are getting the memory address for each of the hashes rather than the contents when you print them.

use Data::Dumper;
my $result = result_of_some_call();
say Dumper $result;

(BTW you didn't find an API on CPAN; you may have found a client to connect to an API ...)

Hope this helps!

(*) Hm, now I see that you may have dumped the struct, did not notice that at first. Not sure about the question in view of that ...
