@OECHO

@oecho <object> [ = <prefix message> ]

Sets the oecho prefix message for <object>. The prefix is prepended to anything a player 'sees/hears' from inside a vehicle or container that's coming from outside the container. Without a message argument, it clears the message. <object> can be specified as <name> or #<number>, or as 'me' or 'here'. This is the same as '@set <object>=_/oecho:[text]'.
