Software maintenance requires understanding existing code, determining whether to make changes, assessing the impact of modifications, rebuilding code after alterations. and regression testing to validate changes. Program understanding is a bottleneck phase when the code to be maintained is invisible. i.e. difficult to get needed information. This paper suggests a method for supporting program understanding by bottom-up driven and code-oriented view. The toolset includes abstraction mechanism, restructuring capability, ripple effect analysis, chunking guidance, and reuse. It lets maintenance programmer understand program effectively, refer other person's understanding, analyse effect of changes, and find reusable program segments.
