Abstract

This paper describes an information storage and retrieval system called LISTAR (Lincoln Information Storage and Associative Retrieval) being implemented on Lincoln Laboratory's IBM 360/67 computer to run under the IBM CP/CMS time-sharing system. An experimental version of LISTAR designed to test its main features was implemented on the IBM 7094 under the MIT Compatible Time Sharing System (CTSS). This version was described in some detail in Lincoln Laboratory Technical Report 377. Because of its experimental nature, the CTSS version of LISTAR limited the total space for data files to the non-program space available in core memory. The current version allows the file space to extend beyond core memory to auxiliary storage. The logical limit of this space is determined by the addressing capacity of the system. File space size is currently fixed at 230 (1000 million) bytes. This could be increased by relatively minor program changes. The current version also introduces new techniques in space management to deal with this extended file space.
