... compact and easily retrievable form. Reports and dictionaries stored on disk form the system's data base.CISP consists of a set of modules shared by a, number of specific load module programs which store reports, retrieve them, and process requests. The system was programmed in PL/I on the IBM 360/75 OS computer system. CISP is operated from terminals situated in hospitals.
