/sys$common/syshlp/helplib.hlb CMS, MODIFY, CLASS, Qualifiers, /NAME=class-name  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Specifies the new name for the class. The new class name cannot
    be the same as an existing class or group name. If a previously
    used class or group name has been removed with the DELETE CLASS or
    DELETE GROUP command, you can reuse that name. Wildcards and comma
    lists are not allowed.

    If you specify the /NAME qualifier, you cannot use wildcards or a
    comma list in the class-name parameter, nor can you use a wildcard
    for the /NAME qualifier. You cannot change the name of a class
    that has read-only access.
