Abstract :
The USAF Wright Laboratory and TASC are developing automated and semi-automated capabilities to support the reengineering of legacy weapon system software. To this end, an environment for reengineering software from one source language to another has been developed. The approach reengineers a legacy program into Ada by reusing portions of the original implementation and design and allows the user to improve the overall design by taking greater advantage of the modern features of Ada. The paper shows that by inserting a user into the process, the design of the reengineered system is improved. Maintainability, and other characteristics such as reliability, can be enhanced by reengineering because the user can make design decisions that utilize the modern software engineering features of the target language in ways that are unattainable through a purely automated process
