A RDJFCB macro instruction was issued. A DCB in the parameter list had a blank DDNAME field.
The request for this DCB is ignored and a return code of 4 is passed in register 15.
Correct the errors causing the DDNAME field to be blank and run the job step again. The error is usually caused by not specifying DDNAME= when coding the DCB.
