VMS Help CMS, MODIFY, GROUP, Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The MODIFY GROUP command changes the characteristics of one or
    more groups. You can alter the following characteristics:

    o  The name of the group.
    o  The access to the group (READ_ONLY or NOREAD_ONLY). You cannot
       change the contents of a group that has been set READ_ONLY.
    o  The creation remark that is associated with the group.

    Use the SHOW GROUP command to display group characteristics.
