/sys$common/syshlp/helplib.hlb SET, RMS_DEFAULT, Qualifiers, /SYSTEM  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Requires CMKRNL (change mode to kernel) privilege.

    Applies specified defaults on a systemwide basis to all file
    operations.

    Systemwide settings are implemented as system parameters, with
    the exception of /QUERY_LOCK. For a systemwide setting to survive
    a system reboot, it must be written to the system parameter file
    by using SYSGEN.
