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

1 - /LOG

       /LOG (default)
       /NOLOG

    Controls whether the system displays a message indicating that
    the key state has been set.

2 - /STATE

       /STATE=state-name
       /NOSTATE

    Specifies the name of the state. The state name can be any
    alphanumeric string. If you omit the /STATE qualifier or use
    the /NOSTATE qualifier, the current state is left unchanged. The
    default state is DEFAULT.
