I am seeing the last statement as :
If you omit the DISP parameter, the default is a NEW data set with a disposition of DELETE for both normal and abnormal termination disposition. Thus, you can omit the DISP parameter for a data set that is created and deleted during a step.
How it will help us in which this dataset has the lifetime only at a particular step?
How it differ from a temporary data set that will be deleted after the job
ends?
Please clarify
Thanks in advance |

| A temporary data set can be referenced in subsequent job steps, which is often helpful. DISP=(NEW,DELETE,DELETE) means the data set cannot be used outside the one job step. |

Consider this a "work file" for use only by the particular step. Often used when there is too much data to load into an array within the program. |
