[Pdx-pm] Pass by reference(?)

I think I've got the correct terms but a very weak understanding.
I'm using HTML:Template to fill in some HTML (go figure) and XML
templates. I use a hash to hold the template variables and then use this
construct.
my $add_plans = HTML::Template->new(
filename => "$TemplateDIR/$Template",
die_on_bad_params => 0);
foreach my $key (keys %SUI) {
$add_plans->param($key => $SUI{$key});
}
And though it's only 2 lines of code it goes (to my way of thought)
against the grain. I'd like to do something like a fill_form subroutine
that I could call. The hash (%SUI) is global (main) but $add_plans is
local to the subroutine it is in.
So my question(s) are how to call the sub and how to access the
variables.
My thoughts are
&fill_form(\$add_plans, %SUI);
I do realize I can get by without passing the %SUI since it's global
but it seems good form and probably should be \%SUI with then the
subroutine would be completely generic.
But I'm completely out of my depth when it comes to the actual
subroutine and how to get at $add_plans and if I need any special magic to
return it.
As always any and all help, pointers and clue-stick are appreciate.
