1. If Rlock() make sure to issue Unlock
2. Why do you need to lock the record? For sure to one will be accessing it because you are the one who added to the table.

CLOSE TABLES ALL
SET SAFETY OFF
CREATE TABLE MyTable (MyField C(10))
USE
USE MyTable
SCATTER MEMVAR BLANK
INSERT INTO MyTable FROM MEMVAR
RLOCK()   && Comment this line and it works properly
REPLACE MyField WITH "TEST"
UNLOCK IN mytable
SELECT * FROM MyTable WHERE MyField = "TEST"
