Session VI Contributed Papers: Programming Languages And Systems


PEPL (Psychology Experiment Programming Language) is a real-time, on-line experimental control system designed for a 4K PDP-8 computer with minimal additional hardware. The system, consisting of the PEPL language, a symbol table for standard DEC assemblers, and an operating system, is capable of asynchronous, timed control of multiple subjects or experiments. The language offers the user high-level instructions for execution control, computation, timing, and I/O control.
