Abstract

Recently, a refinement calculus called ZRC has been proposed for Z; it follows the style and conventions of the Z notation and is completely formalised. As any other formal technique, however, it needs tool support to be of practical use. In this paper, we present such a tool, which we call ZRC-Refine. It is an interactive tool, whose design makes it distinctively user-friendly. We believe that ZRC-Refine is a significant encouragement to the extended application of ZRC and of Z itself.
