VERIFY command.

Verify VSAM Dataset

If a job terminates abnormally and a VSAM dataset is not closed, the catalog entry for the dataset is flagged to indicate that the dataset may be corrupt.  Before the dataset can be opened again, the VERIFY command must be used to correctly identify the end of the dataset and reset the catalog entry.

Model syntax for the VERIFY command:

VERIFY {FILE(ddname[/password])  |     DATASET(entryname[/password])}

With FILE we specify the DDNAME and with DATASET we specify the actual DATASET name.
