The LOCK-LATCH field in the command area must be set to a unique value when a table is opened for write if the user wishes to maintain exclusive update control of the table over successive transactions. See 9. LOCK-LATCH (8 bytes) for more information.

If the LOCK-LATCH password is lost or forgotten, the table can be accessed with the master password in the LOCK-LATCH field. See your tableBASE administrator for more information.
