A conceptual design and implementation plan for VIEW (Video Information Exchange Window), an interactive computer program designed to interface between a graphics terminal user and his executing program to display and manipulate whatever local or remote database he may access. VIEW assists in a wide variety of actions. It can plot contour maps and construct original graphics. There are no restrictions on program type or syntax. Default values are provided for all options. Operating in parallel with the user's program, VIEW converses with it through a simply structured data file, the picturefile. The user can freely modify and annotate any display from the terminal, and can obtain hardcopy of any display and a listing of the variables. Designed to cope with the mass of data produced by climate dynamics simulations, VIEW is modular to permit piecewise implementation with user feedback. The device-dependent portion is insulated from the rest, for transferability. PDP-10 implementation is planned. 44 pp. Ref.
