Abstract: A computer-implemented method is described for displaying on a screen, a plurality of views of a software code listing. The method includes the steps of displaying a first view-type of at least a portion of the software code listing and selecting and displaying additional view-types of the software code listing. The system includes a prioritized listing of view-types, each view-type providing a different presentation of a code listing. When a program listing in one file presents a call to another file, the system automatically presents a window including the called code listing, with the view-type automatically selected in accordance with the preestablished priority listing. Windows/code views are handled as objects, and are thus immediately recallable using a graphical interface.
