This book is about the Tele-Communications/Data Management System (TCDMS). It was written to provide TCDMS users with the information necessary to understand and evaluate the facilities of the system. The Tele-Communications/Data Management System is a data communications system which acts as an interface between application programs and the resident IBM System 360/370 OS or VS operating system. It consists of two major components; a set of telecommunications modules which controls the processing of all transactions through the TCDMS network of terminals, and a set of data management modules which controls the placement, manipulation, and retrieval of information in the TCDMS integrated database.
