@find

command: @find <name>[,<low>[,<high>]]

displays the name and number of every room, thing, or player that you control whose name matches <name>. because the command is computationally expensive, it costs 100 coins.

<low> and <high> may be used to restrict the range of objects that are searched, if they are given then the search starts at object #<low> and ends at object #<high>.
