The purpose of this study is to produce a metric to accurately capture the effects of real time dispatching using object-oriented (00) programming applied in the maintenance phase of the life cycle of hard, real-time systems. The hypothesis presented is that object-oriented programming constructs can be applied in a manner that will have beneficial life-cycle maintenance effects while avoiding adverse timing side effects. This study will use complexity measures instruments that will calculate the Cyciomatic Complexity. This study will examine the dispatching time of each program, and utilize utilities to calculate the number of machine cycles for each program component. Coding techniques will be presented for various program design dilemmas, which examine the object-oriented dispatching features.
