you place a \ in front of what you are doing, so it becomes
&foo(\%bar);
No real need to return, since any updates you would do, automatcially upd
the hash. Within the sub foo you would have somehting like:
my ( $bar ) = @_;
To access using a key:
$bar->{'key'} or could be a variable
$bar->{$mykey}
Wags ;)

Subject: passing hashes between subroutines
Is it possible to pass hashes between subroutines? When I try stuff like
&foo(%bar); or return %bar; it doesn't seem to work how I would expect.
