SQL & PL/SQL

I'm executing the following procedure call:

DECLARE
i_rgsc varchar2(4) :='0106';
i_kcrule varchar2(3) :='012';
o_sale_rec pkg_rule_sale.salepool_tab_type;

BEGIN
sp_rule_sale(i_rgsc, i_kcrule, o_sale_rec); END;

The output parameter, o_sale_rec is declared as a package of type table. How can I view the results of this output parameter. I'm actually trying to show my result in a DBGRID. If anyone knows how to do this or an alternative method of doing this in Delphi with DOA please let me know
