Hi Monks,
I am trying to use copy a list from a reference hash. I am passing the hash to a subroutine as a reference.
I can copy individual items from the hash without a problem but I cannot figure out how to copy the list contained in the refence.
This is what I have tried.


my %Point = ('E' => [0,1,2],  'ID' => 'X30Y30VX11VY15E15');
&SomeRoutine(\%Point);

sub SomeRoutine {
    $P = shift;
    $id = $$P{'ID'};
    @e = $@{$P{'E'}};

When I use this code the copy of the list returns back the following error:
Use of uninitialized value in hash element
