A COPIES parameter on a sysout DD statement overrides an OUTPUT JCL COPIES parameter.

If this DD statement references an OUTPUT JCL statement and that OUTPUT JCL statement contains a FORMDEF parameter, which specifies a library member, the COPYGROUP parameter on a FORMDEF statement in that member overrides any group-value subparameters on the OUTPUT JCL COPIES parameter or the sysout DD COPIES parameter. For more information, see FORMDEF parameter.
