Yeah I was reading about references... AHHHH
i don't get it...
I fgured I could just breah the hash into two arrays, pass them and
reconstruct the hash in the package.. of something like that...
will read more tomorrow..maybe some sleep will make it all make sence!LOL
thanks
Lou

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.
