JES3 ignores the processing options specified on a default //*FORMAT
statement when a sysout DD statement explicitly or implicitly references
an OUTPUT JCL statement.
JES3 ignores the processing options specified on a default OUTPUT
JCL statement when a //*FORMAT statement explicitly references a sysout
DD statement.
When a sysout DD statement explicitly references an OUTPUT JCL
statement and a //*FORMAT statement explicitly references the same
DD statement, the processing options from both the OUTPUT JCL and
//*FORMAT statements apply. Two separate sets of output are created
from the data set defined by the sysout DD statement; one according
to the processing options on the OUTPUT JCL and DD statements, and
the other according to the processing options on the //*FORMAT and
DD statements.
