### Format
> `shutdown(Addr,Natural=0)`

### Args
- `Addr`: This is the address of the child world returned by startup().
- `Natural`: Specifies whether to wait for the child world to die naturally, or whether it should be killed with the "Del" world topic. The default value of 0 kills the child, and a value of 1 waits for the child to exit of its own accord.


If no address is specified, the current world is shut down.
