ABSTRACT:
In a programmed computer system, normal processing results generated by a called method are returned to one or more calling methods by an exception rather than by the more conventional single-type return value. The programmer is granted flexibility through the ability to use multiple normal return types while retaining strong data typing. Better programming practices are promoted through the use of a single exception-technique for handling normal results as well as abnormal (i.e. error) results. The disclosed technique can be used with existing programming languages/environments such as the Java® language, and can provide a basis for new languages/environments that are specifically tailored to this processing technique.
