State-Transition Programming Techniques and Their Use in Producing Teleprocessing Device-Control Programs

A method of using state-transition diagrams for writing and implementing control programs for teleprocessing devices is presented. Currently used techniques are briefly compared with this method. The simple example of reading a teletype is discussed. The technique is evaluated solely upon ease of program preparation and resource optimization is not considered. Generalizations and extensions of the technique are suggested. A detailed example of a state-transition program controlling an IBM S/360 channel-to-channel adapter is presented in the Appendix.
