A very high-level trace for data structures is one which displays a data structure in the shape in which the user conceptualizes it, be it a tree, an array, or a graph. GRAPHTRACE is a system that facilitates the very high-level graphic display of interrelationships among dynamically allocated Pascal records. It offers the user a wide range of options to enable him to "see" the data structures on a graphics screen in a format as close as possible to that in which he visualizes it, thereby providing a useful display capability when the user's conceptual model is a directed graph or tree.
