ISMSEQUENTIALWRITE updates the file with your record and updates all key tables. Recovery information is saved before the key tables are updated. A WRITE operation physically updates the keyed file. ISMSEQUENTIALWRITE does not affect the current record pointer.
The ISMSEQUENTIALWRITE procedure requires the following parameters to return a sequential WRITE result:
ISMSEQUENTIALWRITE (ISAMFILE, RECORD)
-
ISAMFILE—The user's file.
-
RECORD—The user's record area.
