Describes the benefits of interactive computer graphics to FAST-VAL. Interactive graphics facilitates and therefore reduces the errors in deployment of resources for this complex model. An interactive program permits the user, seated at a CRT console, to enter new data and to study or even modify the program while it is running. The FAST-VAL Ground Unit Deployment Input System was designed to use an IBM 2250 graphic console attached to an IBM 360/50 computer. The console displays a grid representing an area divided into 100-ft squares. The interactive system enables the user to create and deploy resource symbols, to move them freely around the grid, and to delete them by pressing one of eight lighted function keys: LABEL, SYMBOLS, SELECT, DEPLOY, DELETE, CONVERT, RESTART, and QUIT. 96 pp. Ref.
