Hi, I have a doubt on Hash variable in Perl. In script, I see the below hash defined: 
my %_abc;

[download]
and in some subroutines, I see this: 
$_abc{"info"}->{$env}->{"Generic"}->{"Cat A"}=10;
$_abc{"warning"}->{$env}->{"Generic"}->{"Cat B"}=20;
......

As the first variable is a hash, I suppose the $_abc are values in hash, but what is the use of -> here? Can someone explain to me the meaning of "->" here? My understanding is the elements of a hash are key/value pairs, thus, why we have 3 "->" here?
