Use of Multiple On-Line, Time-Shared Computer Consoles in Simulation and Gaming

A progress report on the interactive use of on-line, time-shared JOSS computer consoles in war gaming at RAND during the six months since publicly accessible files were added to JOSS capabilities. By programming consoles to interrogate certain files periodically, a crude but highly serviceable real-time store-and-forward communication system is created. The simple JOSS programming language is perhaps the most important feature, since it makes it possible for game players to contribute to the improvement of programming. When the automated Tactical Air Control System simulation was exercised by five Army ROTC students, the Litton Digital Message Entry Device (DMED) format proved too rigid to cover all FAC information needed, and that the Fighter Duty Officer needs three CRT displays: for FAC requests, aircraft status, and his own assignments of aircraft to missions. A text-only diplomatic message simulation and a data-only sub-launched missile duel are also included. Teletype consoles (Type 33 and 35) can be used as JOSS consoles, permitting participation, regardless of location, through conventional teletype or dataphone connections.
