Okay, I was thinking of creating a package "Common" that would hold the state variables. Can you "set" a variable in a package and be able to retrive it later if you maintain the pointer to the package? For instance..

package Common;
my $session;

#main program
$comm=new Common;
$comm->session="1234";
$temp=$comm->session;
print "$temp";

would this print out 1234 or can you not assign variables inside packages like this? Thanks.
