Delete Datasets

ISPF foreground option 3.2 (Data Set Utility panel) is also used to delete the datasets. However, the IEFBR14 utility is used to delete the datasets as part of a batch run. The dataset can be either a Sequential file(PS) or Partitioned Dataset(PDS).

The disposition to delete the dataset is DISP=(OLD,DELETE,..) or DISP=(MOD,DELETE,..).

DELETE option performs below two tasks -

• Deletes an entry from the system or user catalog directory for the dataset.
• Removes the dataset entry from VTOC (Volume Table of Contents), and it cant be retrieved.
• Removes all the required indexes that are required to access the dataset.

Syntax -
