TO MEET the increasing demands from its patrons for automation equipment, the Western Union Telegraph Company has completed the design of an extremely versatile data control system for use with high-speed electronic computers at centralized integrated data-processing (IDP) centers. This system serves as the main artery for data information which can be transmitted simultaneously from cities throughout the country over a Western Union telegraph network. As each unit of classified information is received, it is automatically processed into the proper data category for efficient and high-speed programming by modern computers.
