LOCK field

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.

Cautious use of this mechanism is strongly encouraged—bypassing the system’s controls on multiuser write access is rarely necessary.
