Abbreviation: DS

You can use the VERIFY command following a system error that caused a component opened for update processing to be improperly closed. You can also use it to verify an entry-sequenced data set defined with RECOVERY that was open in create mode when the system error occurred. However, the entry-sequenced data set must contain records (not be empty) to successfully verify.
