The practice of software development continues to shift towards the use of object-oriented approaches. The motivation for this trend is the benefits attributed to object-oriented software, including improved maintainability. As organizations develop new object-oriented software, they face the problem of maintaining their older software. How can existing non-objected-oriented software benefit from this new software engineering technology? This paper presents a nine step process for deriving an object model from existing unstructured FORTRAN source code. Both top-down and bottom-up approaches are used to derive objects, classes, class attributes and methods, and relationships among classes. This process can be used within a reengineering project to convert legacy FORTRAN code into a new object-oriented implementation written in a language such as C++. Experience with using this process is also described.
