       /STATE[=state-name]
       /NOSTATE (default)

    Specifies a key state to be established as the current state.
    You can specify a predefined key state, such as GOLD, or
    a user-defined state. A state name can be any appropriate
    alphanumeric string. The /NOSTATE qualifier leaves the current
    state unchanged.
