            Abstract

            We present a generalisation of data refinement in Z, called IO-refinement , that allows changes in input and output parameters of operations. Several informal motivations for the desirability of such a refinement relation are given, followed by a formal derivation that demonstrates its theoretical soundness. It is proved that IO-refinement indeed generalizes data refinement. Several theorems are presented that give sufficient conditions for IO-refinement to hold in simpler situations, e.g. just adding inputs and outputs. Some examples of the use of IO-refinement are also given.
