Relationship to sysout DD and OUTPUT JCL statements

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.
