AN ON-LINE CONVERSATIONAL RETRIEVAL SYSTEM FOR ORCHIS TEXT-ORIENTED DATA BASES USER'S MANUAL

摘要

This report is a user guide to the 0RL00K computer program. It includes descriptions of information files, methods of com¬munication, program functions, control command syntax, and frequently used terminology. The program was developed as an integral part of the Oak Ridge Computerized Hierarchical In¬formation System (ORCHIS) to facilitate retrospective searches of online linear files. It executes in the timesharing tele¬processing environment of the IBM 360 Model 75 computer at the Oak Ridge National Laboratory. Subset files produced from its logical operations can be searched, combined, copied to online storage for subsequent ORCHIS manipulation, and output to the user typewriter terminals or to the computer system printer.
