An associated LU table contains associated LU names that can be passed to VTAM® application programs in their LOGON exits. VTAM application programs use the associated LU names to create dynamic definitions for their session-partner resources. These names specify primary and alternate printers that are logically related to the SLU. This information is not available in model definitions. For information on model definitions, see Model name table.
Operands on an SLU’s resource definition can associate that SLU with the proper associated LU data. The ASLTAB operand specifies the associated LU table to be used, and the ASLENT operand specifies the proper entry within the table. These operands are described for each LU-type resource in "About this topic".
