in reply to How can I grab all CGI variables at once? (was: CGI)

From the documentation of CGI: 
       FETCHING THE NAMES OF ALL THE PARAMETERS PASSED TO YOUR
       SCRIPT:

            @names = $query->param;

....

       FETCHING THE PARAMETER LIST AS A HASH:

           $params = $q->Vars;
           print $params->{'address'};
           @foo = split("\0",$params->{'foo'});
           %params = $q->Vars;
