When should DISP=MOD is used?
Answers were Sorted based on User's Feedback
Answer / guest
DISP=MOD is used to either extend an existing sequential
dataset or to create a dataset if it does not exist. If the
dataset exists, then records are appended to the dataset at
the end of the existing dataset. If the dataset does not
exist, the system treats MOD as if it were NEW, provided
that the volume parameter has not been used. If the volume
parameter is used, the system terminates the job and does
not create the new dataset. MOD can be used to add to a
dataset that extends onto several volumes. Always specify a
disposition of CATLG with MOD for cataloged datasets, even
if they are already cataloged, so that any additional volume
serial numbers will be recorded in the catalog.

Answer / peter
Disp=New tells the system to create a NEW dataset at step
initiation, so that the program can use the newly created
dataset.
The dataset is NOT created at the end of the job-step, "step
termination", but the system looks at the second positional
parameter in the DISP=(NEW,xxx) whether the dataset should
be kept or not!!

disp=old refers to dataset already created.
disp=new refers to dataset to be created at end of this step

dataset if
dataset already present or a new dataset is created if it
is not already present.
