Termination phase
DFSORT runs Major Calls 4 and 5 during the termination phase. Only one call is made at each of these Major Calls.
Note: If a system abend occurs while DFSORT's ESTAE recovery
routine is in effect, and Major Calls 4 and 5 have not already been
run, the ESTAE routine runs them. If an EFS abend occurs during Major
Call 1, the ESTAE routine does not run Major Calls 4 and 5. See DFSORT abend processing for more information about ESTAE.
