摘要：

For programs to be reliable and fault tolerant, each program module must be defined to behave reasonably under a wide variety of circumstances. An exception handling mechanism supports the construction of such modules. This paper describes an exception handling mechanism developed as part of the CLU programming language. The CLU mechanism is based on a simple model of exception handling that leads to well-structured programs. It is engineered for ease of use and enhanced program readability. This paper discusses the various models of exception handling, the syntax and semantics of the CLU mechanism, and methods of implementing the mechanism and integrating it in debugging and production environments.
