& no_command
 
  Flag: NO_COMMAND(n)
 
  The NO_COMMAND flag disables the checking of $-commands on an object.
 
  Most MUXes will be configured to automatically set this flag on rooms
  and players. The server runs faster when fewer objects are checked for
  $-commands; thus, any object which does not have $-commands on it should
  be set NO_COMMAND.
