Exception handler's are one-argument procedures that determine the action the program takes when an exceptional situation is signaled. The system implicitly maintains a current exception handler in the dynamic environment.
The program raises an exception by invoking the current exception handler, passing it an object encapsulating information about the exception. Any procedure accepting one argument can serve as an exception handler and any object can be used to represent an exception.
