throw Value
Args
Value: Any value, which will be sent to catch() if present.
This keyword throws an exception, which will stop executing the current proc and go to the most recent catch block if one is present. The catch block will receive the thrown value. If there is no try/catch in use, the exception will be passed to world.Error() (if present), then the current proc will end and control will return to the caller.

catch(var/e)
world.log << "Exception: [e]"You can use the EXCEPTION macro to create a new /exception datum, which contains a value or message as well as the file and line number where the exception was created. The thrown value does not have to be an /exception datum; you can throw anything, even null.
