Returning multiple values from a C UDR

Is there any way to return multiple values from a C-UDR? I'm interested in the OUT parameters in a UDR definition. It looks like these can only be used in the WHERE clause of one SQL statement. Heres what I'm trying to do in SPL psuedo code. DEFINE v_out_one INTEGER; DEFINE v_out_two INTEGER; DEFINE v_return_val INTEGER; execute function test(1,v_out_one,v_out_two) into v_return_val; -- use v_out_one and v_out_two this will not work with error: 9781: SLV cannot be an argument to a function invoked explicitly byEXECUTE or CALL. Error in line 1Near character position 38 > informix@warhol 107% finderr 9781 -9781 SLV cannot be an argument to a function invoked explicitly by EXECUTE or CALL. A routine that has an OUT parameter can only be invoked as part of a data-management language query (only in the WHERE clause). Do not invoke such a routine with a CALL or EXECUTE statement. I don't think I can do this with out params. I know I can create a collection and return that but in the real scenario I'm returning a lot of data for each output parameter (I would have multiple returned collections!) Thanks for any help or advise.
