I have had a job change, and had to step away from the perl arena for a while. I have start a little script and I am a bit rusty. That being said, I have something that confuses me.

I have a HoH: %hash
%hash has 5 keys that are also hashes (%key1, %key2, %key3, %key4, %key5)
each of these hashes have 5 keys/value pairs.

When I undef(%hash) and I do a key count on it
$count = keys %hash;
$count = 0 and I would expect this. But when I do a key count on the hashes one level in:
$count = keys %{$hash->{$key1}};
I get $count = 5. This I did not expect!

I know that I can loop through the hash and undef everything, but why is this happening? What am I missing?

I did a super search and did not see this discussed.

Thanks in advance!
