VMS Help DEFINE, Qualifiers, /GROUP  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Requires GRPNAM (group logical name) or SYSNAM (system logical
    name) privilege to place a name in the group logical name table.

    Places the logical name in the group logical name table. Other
    users who have the same group number in their user identification
    codes (UICs) can access the logical name. The /GROUP qualifier is
    synonymous with the /TABLE=LNM$GROUP qualifier.

    If you enter more than one of the qualifiers /PROCESS, /JOB,
    /GROUP, /SYSTEM, or /TABLE, only the last one entered is
    accepted.
