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 Z controller JCL procedure. 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.
