Explanation

In JCL, if the DISP parameter is omitted, the default disposition is (NEW,DELETE,DELETE) for new datasets. This means the dataset is treated as new, and will be deleted in both normal and abnormal termination conditions. Default dispositions prioritize cleanup over keeping datasets that aren't explicitly managed.
