A new computer system is now under development at the Center for Research in Management Science (CRMS) of the University of California, Berkeley. It is an inexpensive, medium-scale time-sharing system, whose primary application is the implementation of multiterminal, interactive simulation experiments for the purpose of social science research. This paper describes the APL-language subsystem implemented on this system. The CRMS APL language system includes a microcoded APL interpreter which is implemented on a high-speed microprocessor. In addition to an extremely high rate of execution, CRMS APL offers a unified facility for terminal input/output, file accessing, and multi-process synchronization and inter-communication in APL.
