in reply to References for subroutines to Hashes in Hashes :)

You are very close. The trick to remember is that hashes and arrays can only store scalars. Perl can have complex data structures only because a reference is a scalar.

This means that your hash of hashes is really a hash of references to hashes. To pass the reference to a subroutine, then, you need only access the value. In this case simple remove the preceding slash ( sorry, I would try to use a code tag, but I am using Opera and it makes a real mess of things ).

Hth,
mikfire
