in reply to RFC How to retrieve a hash from a hash of hashes

'I still find some things hard to figure out...'. Welcome to the club. There is always going to be something difficult. However, the best way I have found to reduce the frustration factor is to look for a tutorial or the right book. For dealing with hashes and getting a 'big picture' of how they work I recommend Effective Perl Programming. It has pretty pictures that show you how data types in Perl are represented as well as example code of operations you will find very useful.
