The basic simulation language is the analog-like, block-oriented language PACTOLUS, originally written for the IBM 16N computer. CIDAS adds to PACTOLUS a control program which permits the operator to modify the problem state ment by means of the console typewriter. The control program permits the user to make changes in time is tervals, configurations, parameters, output variables, and intrinsic storage variables. The program, on request, W;l inform the user of any options available to him during interruption of the configuration.

    CIDAS appears to be a useful improvement of a widely known block-oriented language, primarily suitable for training users of small computers. (The paper does not specify the computer on which the system was run; to only indication is the heading of the sample printout, "1 Converted Iterative Digital Analog Simulator/360.")

    A special note to acronym specialists: CIDAS (Conversational Iterative Digital/Analog Simulator) is a direct descendant of DAS (Digital/Analog Simulator) and MIDAS (Modified Integration Digital/Analog Simulator), developed at Wright-Patterson Air Force Base for the 1094 computer. A reduced version of MIDAS, specifically written for the IBM 1620, was named PACTOLUS, which was not an acronym at all, but rather the name of the liver in which the mythological King Midas bathed to remove his golden touch.
