A data structure display device and method

摘要

A system and a method is disclosed that ensure the visual and intuitive understanding of the data structures of a program and the arrays in a memory area. A user uses a mouse pointer and clicks it on a data item in a program to select the data item. A system calculates offset data for each data item defined by a program. When there is a data item that is used for re-definition, the offset for a data item to be re-defined is added to the offset data to provide an offset value. The data items are arranged in order according to their hierarchical relationship, and data items that have the same offset are displayed as a single line. A numeral for an offset is added to the line, and a broken line is used to separate lines of data items.
