@ACTION

@action <name> = <source> [ = <regname> ] (Builders only.)

Creates a new action and attaches it to the thing, room, or player specified. If a <regname> is specified, then the _reg/<regname> property on the player is set to the dbref of the new object. This lets the player refer to the object as $<regname> (ie: ) in @locks, @sets, etc. You may only attach actions to things you control. Creating an action costs 1 penny. The action can then be linked with the command @link.
