Installing the exit
The load module implementing the job-library-read exit must be link-edited into an APF-authorized library in the LNKLST concatenation or defined by the STEPLIB DD statement in the HCL Workload Automation for Z JCL procedure. The load module should be link-edited with RMODE(24) according to normal z/OS restrictions.
Note: EQQUX002 must be coded REENTRANT if the value of the
GSTASK keyword on the OPCOPTS statement is greater than 1.
