State-transition programming techniques and their use in producing teleprocessing device control programs

The problems of writing programs for complex and timing dependent processes are discussed and programming techniques using state-transition diagrams are defined. It is shown that programming effort can be reduced by these techniques. Their use in writing teleprocessing device control programs and many other programs is discussed. It is shown that programs written using these techniques are extendable to more general application. A Binary Synchronous Communications multileaving control program in the Pitt Time Sharing System implemented by using these techniques is discussed. A considerable reduction of programming effort was realized for this implementation.
