    Description

    Title : A Calculus of Program Modifications
    Abstract : It is common to distinguish between two paradigms of software reuse: black box reuse, which consists in reusing components verbatim, without modifying them; and white box reuse, which provides for making modifications to retrieved components before using them. Because software components are very information-rich (i.e. it takes a great deal of information to characterize a component), the chances of an exact match between an available component and a query are in general very slim; hence it is necessary to make provisions for adapting retrieved components to user requirements. This paper discusses a mathematical foundation for carrying out this modification process in a correctness-preserving manner. 1 Introduction: Why Do We Need Program Modification?
