I Need to Return Two values or more from Function, Is this possible?

Question

Below is the offending query, I am trying to pass v_bu and v_po to this function, and after validations then return v_count and v_action is this possible in a function? I am having problem returning two values.
see below code
function po_edi_func(v_bu purchase_order.business_unit_id%type,
     v_po purchase_order.purchase_order_number%type)
     return number as pragma autonomous_transaction;
     v_count               number;
     v_ctdel               number;
     v_action          varchar2(1);
begin
select count(*)
into v_count
from sewn.purchase_order
where business_unit_id=v_bu
and purchase_order_number =v_po;
if v_count > 0 then
     select count(*)
     into v_ctdel
     from sewn.purchase_order
     where business_unit_id=v_bu
and purchase_order_number =v_po
     and purc_orde_status = 1;
     if v_count <> v_ctdel then -- ALl PO's Cancelled--
     v_action := 'U'; -- - NOT ALL PO DELETED --
     else
     v_action := 'D'; -- DELETED ALL PO--
     end if;
else
     v_action := 'I';-- New PO INSERT--
end if;
commit;
return v_count;
end;

Paul,
This is becoming a nightmare to me, can you look at the below and tell me where I am having a problem
This is the Function below
CREATE OR REPLACE function po_edi_func(v_bu sewn.purchase_order.business_unit_id%type,
     v_po sewn.purchase_order.purchase_order_number%type,v_action_out OUT VARCHAR2)
     return number as pragma autonomous_transaction;
     v_count               number;
     v_ctdel               number;
     v_action          varchar2(1);
begin
select count(*)
into v_count
from sewn.purchase_order
where business_unit_id=v_bu
and purchase_order_number =v_po;
if v_count > 0 then
     select count(*)
     into v_ctdel
     from sewn.purchase_order
     where business_unit_id=v_bu
and purchase_order_number =v_po
     and purc_orde_status = 1;
     if v_count <> v_ctdel then -- ALl PO's Cancelled--
     v_action := 'U'; -- - NOT ALL PO DELETED --
     else
     v_action := 'D'; -- DELETED ALL PO--
     end if;
else
     v_action := 'I';-- New PO INSERT--
end if;
commit;
v_action_out := (lpad(v_count,8,'0')||lpad(v_action,1,' '));
return v_action_out;
end;
and this is how I am calling it from my trigger which has to pass the v_bu and v_po values to be used in extracting data and returning the records
see below
if po_edi_func(v_bu,v_po) <> '' then;
v_count:= (substr(v_action,1,8));
v_action := substr(v_actione,9,1);
else
v_count:=0;
v_action := 'I';
end if;
I need the extracted values of v_count and v_action for my app to reset some values
