# Del proc (world)

Source: https://ref.dm-lang.org/world/proc/Del

### Format
> `Del()`

### When
> Called when the world is shutdown.

### Default action
> Shutdown the world.

When the world is destroyed, only the Del() proc of the `world` object is called automatically. If you want to delete any other objects, you must do so from within `world/Del()`. Once this procedure returns, any other procedures which may still be executing are immediately aborted and all objects are silently destroyed.

To prevent accidental hangs during `world/Del()` from preventing shutdown, a timeout is applied to any sleeping operations such as `sleep`, `world.Export()`, and so on. If the total time slept exceeds the timeout, `world/Del()` is aborted. Currently, this timeout is set at 30 seconds.
