throw(ERROR code, STRING explanation[, ANY additional])
This function throws an error with the code code in the
calling method, not the current method. The current method does not have
the ability to stop a method originating in itself. The variables
explanation and additional appear in the traceback.
For more information on error handling see
traceback() and
Errors.
Example using throw():
throw(~perm, "Sender is not the system object.");
