VMS Help CMS, MODIFY, GROUP, Qualifiers, /NAME=group-name  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    name of a group that has been set to READ_ONLY. The new group
    name cannot be the same as an existing group or class name.

    /NAME qualifier, you cannot use wildcards or a comma list in the
    group name parameter, nor can you use a wildcard for the /NAME
    qualifier.
