Abstract | |||||||||||||||||
| We propose a practical incremental approach to perform control flow normalization of COBOL/CICS legacy systems using a software renovation factory. The normalization improves the maintainability of such systems. A consequence of our normalization is that we reengineer the interface so that such systems can be accessed via Intranet or Internet. Moreover, the performance of such systems is improved. We applied our approach to a mortgage system written in COBOL and CICS. Categories and Subject Description: D.2.6 [Software Engineering]: Programming Environments---Interactive; D.2.7 [Software Engineering]: Distribution and Maintenance---Restructuring; Additional Key Words and Phrases: Reengineering, System renovation, Interface reengineering, Control flow normalization, Language migration, COBOL, CICS. 1 Introduction Flow analysis is a fundamental prerequisite for many important types of code improvement [11]. Indeed, many proposals for control flow normalization algorithms have b... | |||||||||||||||||
