Explicitly declares a database closed when you are done working with
 it.  FINISH with no parameter also commits all active transactions.
 It is recommended that you use FINISH before exiting from a program.

 Example:

      999-EOJ.
           IF BAD-FLAG = 1
                 THEN
      &RDB&        ROLLBACK
                 ELSE
      &RDB&        COMMIT
      &RDB&    FINISH
                 CLOSE JOBHST-FILE.
                 STOP RUN.

 If you have invoked a database, you have the necessary privileges to
 use the FINISH statement.

 When you use INVOKE to declare databases and then use the
 START_TRANSACTION statement, the Rdb/VMS preprocessors automatically
 attach your process to all the databases you have invoked.  This
 involves some overhead and record locking.  If the FINISH statement
 occurs explicitly in the run-time flow of the program, Rdb/VMS
 detaches from the database mentioned in the FINISH.  If another
 START_TRANSACTION occurs, Rdb/VMS attaches to the databases again.
 Therefore, if your program uses databases sequentially, you can use
 FINISH to close each database as you are finished working with it.
 In this way, Rdb/VMS attaches only the databases you need at any one
 time.

 FINISH ───┬───────────────────┬─┬────────────────┬──>
           └─┬─> db-handle ─┬──┘ └──> on-error ───┘
             └───── , <─────┘

Additional information available:

db-handleon-error

 A host language variable that identifies the database to be accessed.
 Use the db-handle that you associated with the database in the INVOKE
 statement.

 Specifies host language statements or Rdb/VMS data manipulation
 statements to be performed if an Rdb/VMS error occurs.  For more
 details, request HELP on ON_ERROR.

 The following fragment shows how to use INVOKE and FINISH to work
 with two databases:

 &RDB&  INVOKE DATABASE WORKERS =
 &RDB&    FILENAME 'DISK2:[DEPT4]EMPLOYEES'
 &RDB&  INVOKE DATABASE PARTS =
 &RDB&    FILENAME 'DISK2:[DEPT4]PARTS'
       .
       .
       .
 !   [This part of the program can combine data from
      both databases]
       .
       .
       .
 &RDB&  FINISH WORKERS
       .
       .
       .
 !   [This part of the program uses only
      the PARTS database]
       .
       .
       .
 &RDB&  FINISH PARTS

 Between the second INVOKE statement and the first FINISH, you can
 access both databases at once.
