TSR LOCK-LATCH

LOCK-LATCHES are used by tableBASE to protect a table in memory. A LOCK-LATCH is used when the table is opened for write and is needed for any future update or store access once it is set. LOCK-LATCHES are not checked during fetch access. For more information on LOCK-LATCHES see the tableBASE Programming Guide and the tableBASE Concepts and Facilities Guide.
