A program invoked IEBCOPY, supplying a fourth parameter which is not used by IEBCOPY. Some IBM® Utility programs support user IO routines which are passed in a list as the fourth parameter. Since IEBCOPY does not support user IO routines, it does not expect more than three passed parameters.
The severity is 8.
Processing continues.
To prevent this message from appearing, change the program invoking IEBCOPY so that it will not pass more than three parameters. Refer to the z/OS DFSMSdfp Utilities Appendix A for information about dynamic invocation of IEBCOPY and parameters.
