Your question makes no sense. Can you rephrase and include some sample code of what you’re trying to do?

Cheers,
D.

use strict;
use warnings;
use 5.010;

my $arr = [
    { a => 1, b => 2},
    { c => 3, d => 4},
];

say $arr->[0]->{b};

--output:--
2

my $hash = {
    a => [1, 2, 3],
    b => [10, 20, 30],
};

say $hash->{b}->[2];

--output:--
30
