I'm coming from an OO background and had a question about keeping a persistent variable. For those familar with java, you know that you can instantiate a class and have variables associated with that class that you can assign and retrieve values for.
Here's the perl question. I have a main script that checks the cgi params and calls subroutines according to the params. Each subroutine outputs html code that includes the users sessionid and username. Can I have a perl package that would keep track of the username sessionid so that I could reference there values in my subroutines? Or do I have to pass the values, of the sessionid and username to each of the subroutines when I call them.
I was envisioning something like this. 
package Common;
{
my $username,$sessionid;
}
###
#set their values in the main code
$comm=new Common;
$comm->$username=user;
$comm->$sessionid=1234;

subone($comm);
#in subroutines i could call 
subone 
{
print "$comm->$username";
}

Is there a practical way of doing this? Anyway to do it without even having to pass the $comm to the subroutines?
Thanks.
