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) - Desc (value) --Type 2 (key) - Desc (value) --Type 3 (key) - Desc (value) Part Number 2 --Type 1 (key) - Desc (value) --Type 2 (key) - Desc (value) Part Number 3 --Type 1 (key) - Desc (value) --Type 2 (key) - Desc (value) --Type 3 (key) - Desc (value) --Type 4 (key) - Desc (value) --Type 5 (key) - Desc (value) etc... -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
