) AS USUAL CLIPPER
Request Example View Source

Parameters

nRecordNumber (Optional)
Type: Usual
The number of the record number to be locked. The indicated record is locked, and previous record locks are maintained. Note that this can be the current record: explicitly specifying the current record indicates that previous locks should be maintained. If omitted, or NIL or -1, the current record is locked and all previous record locks are released.

Return Value

Type: Usual
TRUE if successful; otherwise, FALSE (although some records still might have been processed).
