TuringTool: a user interface to aid in the software maintenance task

TuringTool is a source program viewing and editing system specifically designed to support the software maintenance task. TuringTool bases all of its views of the program on a single comprehensive viewing paradigm borrowed from program development environments: source text elision. It is shown how this paradigm can be used to represent several kinds of views appropriate to the maintenance of large source programs, including structural views and nonstructural views appropriate to the maintenance task and how it can be extended to allow dynamic creation of complex programmer-specified views using simple set theoretic operators to combine the effects of several views into one. The system exploits the highly structured nature of the Turing programming language to allow seamless viewing of programs consisting of many separately compiled source modules as one uniform source.<
