This manual is designed to provide an introduction and basic guide to the use of IBM's Advanced Text Management System (ATMS), the text processing system to be used for the creation of Australian data bases within AUSINET. Instructions are provided for using the system to enter, store, retrieve, and modify data, which may then be displayed at the terminal, output for the creation of a data base for subsequent information retrieval using STAIRS, or to compile lengthy documents such as reports. The first part of the manual is concerned with terminal operation and procedures for preparing materials for inclusion in a data base; the second part describes additional features, format controls and special formatting techniques, text alterations, and printing procedures for the creation of printed documents. The manual should be supplemented by the "ATMS Terminal Operations Guide" produced by IBM. (JD)
