Library /sys$common/syshlp/nclhelp.hlb set, x25_protocol, group, members  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Default: No DTEs       Value: Set of records

    DTEs at a gateway system that make up the group. Format the
    values to specify a set of records. Each record consists of a
    name that identifies an X25 protocol dte entity and an integer
    (in the range 0 to 9999) that identifies the CUG number assigned
    by the network. If a DTE is already created and enabled and is
    then added to the set of members, it must be disabled and re-
    enabled to service the specified CUG number or BCUG.

    Example:

    set x25 protocol group GROUP-0 -
        members ((dte = dte-1, index = 444), -
        (dte = dte-0, index = 8787))
