/sys$common/syshlp/helplib.hlb CMS, VERIFY, Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The VERIFY command performs a series of consistency checks on
    your library. If you issue VERIFY under normal conditions, the
    command executes successfully, indicating that the information
    in your library is correct. However, if the data in the library
    is invalid, the command returns an error message indicating that
    there is an error in the verification of the library. You can
    use the /RECOVER and /REPAIR qualifiers on the VERIFY command to
    correct some of the errors discovered by VERIFY.

    Recovery and repair transactions are marked as unusual occurrences
    in the library history.
