Yes. (Hint: passing any complex data around is generally best done with the use of references, so that's the area you need to be studying up on.) Pseudocode: my $result = go_do_something_with( \%this_hash ); ... sub go_do_something_with { my $hashref = shift; ... return $result; } You just have to get the hash data back out of $hashref this way. If you need to pass multiple hashes, the same idea applies: my $new_result = act_upon( \%hash_a, \%hash_b, \%hash_c ); ... sub act_upon { my ( $a_ref, $b_ref, $c_ref ) = @_; ... return $result; } And, again, you just need to unpack $a_ref, $b_ref, and $c_ref in exactly the same way you unpacked $hashref in the first example. If you need to pass more complex data structures, this is the general approach to doing so that most people seem to use. -- Chris Devers ¯)làwÓî¬
