& @lock compound COMPOUND LOCKS: Key: <key> & <key> <key> | <key> !<key> ( <key> ) You can make complex locks by combining keys with the logical AND and OR operators (& and ! respectively), or by using the NOT operator. You may also group complex locks with parentheses. Examples: > @lock exit = me & !me An impossible lock, nothing can be both you and not you. > @lock message = me | *recipient Both you and the player recipient may get the msssage.
