in reply to Accessing and printing an array, INSIDE of a hash

This line:

$hash{'key'} = @array;

... does not do what you think it does. Hashes can only take scalar values, not arrays. You can store a reference to the array:

$hash{'key'} = \@array;

... and then retrieve it back. See Data::Dumper for inspecting your data structures, References Quick Reference on how to get at the data.
