1    /ALL

    Deletes all key definitions in the specified state. If you do
    not specify a state, all key definitions in the current state are
    deleted. To specify one or more states, use /STATE=state-name.

2    /LOG

       /LOG (default)
       /NOLOG

    Controls whether a message is displayed indicating that the
    specified key definitions have been deleted. The /LOG qualifier
    (which is the default) displays the message. The /NOLOG qualifier
    suppresses the message.

3    /STATE

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

    Selects one or more states for which a key definition is to be
    deleted. The /STATE qualifier deletes key definitions for the
    specified states. You can specify predefined key states, such as
    DEFAULT and GOLD, or user-defined states. A state name can be any
    appropriate alphanumeric string. The /NOSTATE qualifier deletes
    the key definition for the current state only.

    By default, the current key state is the DEFAULT state. The
    current state can be changed with the SET KEY/STATE command,
    or by pressing a key that causes a state change (a key that was
    defined with DEFINE/KEY/LOCK_STATE/SET_STATE).
