Abstract :
This paper presents a new approach to the use of design patterns for the reengineering of legacy code, using a mapping from procedural design patterns to object-oriented patterns. We show also how object-oriented design patterns can be formalised and correctness conditions for their application derived, in order to justify the preservation of functionality in the reengineering process. We conclude with a case study of reengineering of a legacy COBOL application
