A sysout DD statement can directly or indirectly reference an OUTPUT JCL statement. The parameters on the referenced OUTPUT JCL statement combine with the parameters on the sysout DD statement to control the processing of the sysout data set. See OUTPUT parameter and OUTPUT JCL statement.

SYSOUT cannot specify a code-name subparameter in a job or job step that contains an OUTPUT JCL statement; in this case, JES2 treats the third subparameter as a form-name, instead of a reference to a JES2 /*OUTPUT statement.

Backward references: Do not refer to an earlier DD statement that contains a SYSOUT parameter.
