• When a sysout DD statement implicitly or explicitly references an OUTPUT JCL statement, JES3 ignores any default JES3 //*FORMAT statements in the job. A default //*FORMAT statement contains a DDNAME=, parameter.
• When a JES3 //*FORMAT statement contains a DDNAME parameter that explicitly references a sysout DD statement, JES3 ignores any default OUTPUT JCL statements in the job.
• JES3 uses the processing options from both a JES3 //*FORMAT statement and an OUTPUT JCL statement in a job when (1) the //*FORMAT statement DDNAME parameter names a sysout DD statement and (2) the sysout DD statement’s OUTPUT parameter names an OUTPUT JCL statement. Two separate sets of output are created from the data set defined by the sysout DD statement:
  • One processed according to the options on the JES3 //*FORMAT statement combined with the sysout DD statement.
  • One processed according to the options on the OUTPUT JCL statement combined with the sysout DD statement.

For more information on the use of the OUTPUT JCL statement with JES3, see z/OS JES3 Initialization and Tuning Guide.
