The LOCK-LATCH field of the command line, labelled “L”, holds the eight-character password required to control table updating. This is used to limit table update capability to a particular transaction, user, or terminal.
DK1TDRVC allows data entry to this field, either directly or in hexadecimal on line one (1:), which is then translated to the field with the >L command (see below), giving the user update ability to any table for which the lock is known.
Warning:
Cautious use of this mechanism is strongly encouraged—bypassing the system’s controls on multiuser write access is rarely necessary.
