You can simplify your code by using APPEND FROM command or you can use UNION.

rpcursor = SYS(2015)
CREATE CURSOR (rpcursor)(mainkey I, vendor c(100), amt n(10,2), rp l)

SELECT op_main_key AS mainkey, op_vendor AS vendor, op_amt AS amt, op_py AS rp ;
  FROM o_ord_main WHERE op_py = .t. INTO CURSOR rp_cursor1
SELECT p_mainkey AS mainkey, p_vendor AS vendor, p_amt AS amt, p_py AS rp  ;
  FROM sub_payment WHERE p_py = .t. INTO CURSOR rp_cursor2
SELECT r_mainkey AS mainkey, r_vendor AS vendor, r_payamt AS amt, r_py AS rp  ;
  FROM req_payment WHERE r_py = .t. INTO CURSOR rp_cursor3

SELECT (rpcursor)	
APPEND FROM ( DBF("rp_cursor1"))
APPEND FROM ( DBF("rp_cursor2"))
APPEND FROM ( DBF("rp_cursor3"))

* UNION
SELECT op_main_key AS mainkey, op_vendor AS vendor, op_amt AS amt, op_py AS rp  ;
  FROM o_ord_main WHERE op_py = .t. ;
UNION ALL ;
SELECT p_mainkey AS mainkey, p_vendor AS vendor, p_amt AS amt, p_py AS rp  ;
  FROM sub_payment WHERE p_py = .t. ;
UNION ALL ;
SELECT r_mainkey AS mainkey, r_vendor AS vendor, r_payamt AS amt, r_py AS rp  ;
  FROM req_payment WHERE r_py = .t. ;
INTO CURSOR rp_cursor

INSERT INTO (rpcursor) FROM memvar

command, it only puts zero's into the rpcursor. When I browse rp_cursor1 - rp_cursor3 I do see the information in there. What am I doing wrong here?
