Explanation

DISP=MOD is used for NEW sequential datasets that are to be created or extended. It specifies that the dataset should be allocated in MOD (modify) mode, which allows writing to the dataset. For partitioned datasets, other disposition parameters are used. DISP=MOD is specifically for sequential datasets being created or extended, not for existing datasets in all scenarios.
