my $count = keys %{ $sub_hash_reference };
You can
I'd like to get the number of keys in hash of hashes. I know that I
can do something like $count = keys( %myHash ), but how would I go
about finding the number of keys in a sub-hash?
Alternately, how could I loop through keys in a hash of a hash?
My hash look like:
-Part Number 1
--Type 1 (key)
