Create a hash:
my (%hash) = ( "key" => "value" , "otherkey" => "othervalue" );
Create a reference to said hash:
my $reference = \%hash;
You can also make a hash reference simply in one step with:
my $reference = { "key" => "value", "otherkey" => "othervalue"};
Dereference is simple:
my ( %otherhash ) = %{ $reference };
