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

    Requires SYSPRV (system privilege) or GRPNAM (group logical name)
    privilege.

    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.
