Hi Ron, if I have correctly understood your request, you can get multiple parameters in this way

sub foo {
 my ($query_ref, $session_ref) = @_;
}

. Generally speaking, if you have 10 parameters, and you call mysub(1,2,3,4,5,6,7..10), you can take the parameters in various ways

sub mysub {
my a = shift; #1
my $b = shift; #2
... and so on

 sub mysub {
 my @p = @_; #the array 1,2,3....10
...

and in your case

 sub mysub {
my ($a, $b, $c, ....$j) = @_; #$a = 1, $b = 2, ... $j = 10

I hope you help.
