Abstract : The report discusses the design and use of the Systems Engineering Laboratory's Markovian Analyzer (SELMA) system for a DEC 339 computer display terminal. The system provides interactive graphics support for a program which was developed concurrently for the IBM 360/67 to analyze a class of Markovian quequeing networks. Special features of the system include handling of all graphic operations at the terminal and recognition of patterns of motion of the light pen to provide a human-oriented drawing capability.
