示例：
CREATE CURSOR T1 (EMS C(13),XM C(10))
INSERT INTO T1 (XM) VALUES ("12345")
INSERT INTO T1 (XM) VALUES ("23456")
INSERT INTO T1 (XM) VALUES ("34567")
INSERT INTO T1 (XM) VALUES ("45678")
INDEX ON RECNO() TO REC

CREATE CURSOR T2 (EMS C(13))
INSERT INTO T2 VALUES (REPLICATE("1",13))
INSERT INTO T2 VALUES (REPLICATE("2",13))
INSERT INTO T2 VALUES (REPLICATE("3",13))
INSERT INTO T2 VALUES (REPLICATE("4",13))
SELECT T2

SET RELATION TO RECNO() INTO T1
SCAN
     REPLACE EMS WITH T2.EMS IN T1
ENDSCAN
SET RELATION TO
SELECT T1
