Using Feature Direction in Understanding Legacy Programming Code
Srinivasulu Mannem, S Rajyalakshmi · 2013
Understanding and maintaining legacy COBOL systems are still a challenging task for both academic research and industry practice. With the development of future direction software engineering, Future direction code comprehension and reengineering for COBOL software systems become a very promising research direction. In this paper, context feature and error handling feature, which are two most important features for COBOL code understanding, are defined. In addition, the advance for feature location and operations in COBOL code is reachable. Program slicing technique is adopted to locate feature code from large COBOL systems. This study/paper reports our experience to date on the application of Feature Direction program understanding in COBOL code.
