A general experiment programming system for the IBM 1800

A system is described that meets some user requirements of programming ease, general applicability, and simultaneous multiple S and laboratory operation. The system is based on an extremely flexible time-sharing real-time monitor and a user-level task-oriented programming language which together free the user from all multiple S bookkeeping programming. The conceptually simple language consists of simple commands for operations at the level of experimental procedure, such as displaying stimuli, collecting and timing responses, providing time delays, and recording data. Other commands support string manipulation, arithmetic, and disk I/O. The system is programmed only for the IBM 1800; however, it represents a successful approach to laboratory computerization.
