VERIFY—Synchronize end of data z/OS DFSMS Macro Instructions for Data Sets SC23-6852-02 |
||||
Use the VERIFY macro to synchronize end-of-data. VERIFY is not supported for z/OS UNIX files and returns an error if specified for these files. The format of the VERIFY macro is:
If you do not specify ACTION=REFRESH for an extended data set, you must close the data set and reopen it to obtain new extent information before you can verify it. Any attempt to issue the VERIFY macro against a linear data set (LDS) results in a logical error (return code 253 in the feedback field of the RPL). RLS does not support VERIFY because RLS maintains the end of data set information in the control blocks. After verifying a data set, positioning must be established with a POINT macro for sequential processing or with a GET macro with RPL OPTCD=DIR. |
