摘　　要：Reengineering legacy systems written in conventional procedural languages to equivalent OO systems makes software more maintainable and reliable. This paper proposes a method for extracting objects from legacy Ada83 systems using module features. First, metrics are developed to measure module cohesion. Then, effects on cohesion from changing module components are analyzed and rules about how to extract inheritance relations among objects are given. At the end of this paper, an object-extracting algorithm using module features is proposed.Reengineering legacy systems written in conventional procedural languages to equivalent OO systems makes software more maintainable and reliable.
