When you specify IEFSD087 as the output writer on the SYSOUT= parameter
of the DD statement, or when you leave this parameter blank, control
will pass to the IBM-supplied output writing routine in module IEFSD087, and it:
Note: When writing multiple data sets to a PDS/PDSE member, if the
‘end-of-output-data-set’ condition arises, the output external writer
cannot guarantee (even if you set CERTIFY=Y as a startup parameter)
that all records will be saved. The current data set is saved, but
all records written up to that point cannot be recovered in the case
of writing to a PDS/PDSE member.
The following diagram shows the general flow of the IBM-supplied output writing routine: Figure 1. General Flow of IBM's Output
Writing Routine
