Pagination or Media Count:
The concepts involved in building and manipulating a data structure through graphical interaction are presented, using the drawing and editing of electrical circuits as a vehicle. The circuit drawing program was designed to operate on an ARDS storage-tube display terminal attached to the Project MAC IBM 7094 Compatible Time-Sharing System. The graphics software system GRAPHSYS was used for dealing with all graphical input and output, and the AED Language of the Project was used in programming. AED System packages for building and manipulating complex data structures are described and their use is illustrated in detail. The report includes flow diagrams and complete listings of the sample circuit drawing and editing system. Author
