Installing the exit
The load module implementing the JCL-imbed exit must be link-edited into an APF-authorized library in the LNKLST concatenation or defined by the STEPLIB DD statement in the IBM Z Workload Scheduler started task.
The load module can be link-edited with either the AMODE 24 or AMODE 31 attribute. IBM Z Workload Scheduler invokes the exit in the addressing mode defined by the exit load module.
