@LOCK @lock <object>[/<attr>]=<key>. Locks <object> to a specific key(s). <object> can be specified as <name> or #<number>, or as 'me' or 'here'. Boolean expressions are allowed, using '&' (and), '|' (or), '!' (not), and parentheses ('(' and ')') for grouping. To lock to a player, prefix their name with '*' (ex. '*Igor'). The optional <attr> argument specifies which lock attribute to use, and can be either "lock" or "elock". This defaults to "lock" (See ENTER). Locks can be set for or against wizzes by using "flag:WIZARD" for an object name, and set for or against robots by using "flag:ROBOT". See the examples.
