i see this on the help

To enable optimistic locking of multiple records in the current work area

Use this function and value:

CURSORSETPROP("Buffering", 5)

Visual FoxPro writes the records to a buffer and permits edits until you issue a TABLEUPDATE( ) command. Visual FoxPro then performs the following sequence on each record in the buffer:

if i do this

sele 1
use plplfmae
.
.
.
.
INSERT INTO plplfmov (A, B, C,D) ;
   VALUES (1, 2, 3, 4) wHERE .....
.
.
.
.

where i put this function ? if the insert command goes to another table?
CURSORSETPROP("Buffering", 5)
