You can define multiple LNKLST sets, but only one LNKLST set is current in the system at any time. Any job or address space that is started after the current LNKLST set is activated is associated with the current LNKLST set. The job or address space continues to use the current LNKLST set until the LNKLST set for the job or address space is updated. (See the parameter description for LNKLST UPDATE.)
