I copy this DISP everywhere and pretend I understand it. Can someone break down the three parts in plain English?
Thread: JCL and JCL Utilities
What does DISP=(NEW,CATLG,DELETE) actually mean?

Status, normal end, abnormal end.
NEW = create it for this step
CATLG = if step works, keep it and catalog it
DELETE = if step abends, throw it away
Common cousin: DISP=SHR means file exists, share for read.

MOD appends if it exists. OLD wants exclusive use. Getting these wrong is how you wipe a file or get waits.
