System jobs that you control (for example, readers and writers)
are assigned an accounting code of *SYS. Other system jobs that you do not
control (for example, QSYSARB, QLUS,SCPF) do not receive a journal entry.
Note: You cannot use the Change Accounting Code (CHGACGCDE)
command to change the accounting code of the subsystem monitor or a reader
or writer. You can, however, change the accounting code of a reader or writer
by changing the appropriate IBM-supplied job descriptions and user profiles
and then starting them again.
