Abstract
This paper deals with the specification of communicating systems and their stepwise transformation into occam-like programs. For communicating systems a model similar to Hoare's CSP is used. First a specification language is given, which is particularly suitable for describing communicating systems. A quite simple readiness semantics allows to specify the users' wishes in an exact but easily expressible manner. Secondly aspects of a development approach are shown, how to achieve programs satisfying these specifications. For this purpose transformation rules are given whose applicability can be checked syntactically. Their correctness can be proved on the basis of readiness semantics and predicative semantics for the programming language. The main characteristics of the approach are illustrated by examples.
