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

    Specifies the new name for the group. You cannot change the
    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.
    Wildcards and comma lists are not allowed. If you specify the
    /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.
