Installing the exit

The load module implementing the JCL-variable-substitution exit must be link-edited into a library in the LNKLST concatenation or defined by the STEPLIB DD statement in the controller JCL procedure. If the exit is used for members of the SCRPTLIB, the library that contains it must be pointed to by the STEPLIB DD statement of the JCL jobs for the daily plan extension, daily plan replanning, and symphony renewal. The load module can be link-edited with either the AMODE 24 or AMODE 31 attribute. Tivoli Workload Scheduler for z/OS invokes the exit in the addressing mode defined by the exit load module.
