Other Considerations

A LOAD step automatically sets the USE-OVRD-LIB value to N whenever it is executed. If a job has JCL in the special override library waiting for the job to be scheduled and a permanent change is made to the master JCL in the normal production library, any load of the JCL causes the USE-OVRD-LIB flag to be reset to N. Therefore, such changes must be avoided, or at least not reloaded with a LOAD top line command, until after the job has been scheduled into the queues with the set of JCL from the special override library.
