When Exit 24 is called, HASPIRA has called each JES2 initialization routine (IR) in turn to perform JES2 initialization. After all the IRs have successfully completed, HASPIRA calls the Exit 24 routine(s) before tracing the JES2 initialization and returning control to the HASJES20 load module (HASPNUC). On return from HASPINIT, HASPNUC deletes the HASPINIT load module (if not part of HASJES20) and passes control to the asynchronous input/output processor, $ASYNC, resulting in the dispatching of JES2 processors.
