Graphic ROCKET, an interactive computer graphics system for aerospace trajectory analysis, is now being developed. It is an adaptation of Rand's Omnibus Calculator of Kinematics of Earth Trajectories. Graphic ROCKET has fewer branches. Thus, an on-line user can wait to see the results of his first run before specifying variations. By reducing the total number of runs required, interactive operations can provide more efficient machine usage, despite the overhead cost, as well as acceleration of the design process. Even a good batch-mode program needs considerable redesign to reorient it toward interactive processing. Emphasis should be on user language, program efficiency, and ease of extending models and considering alternatives. The system designer should not attempt close optimization, but should build a flexible system.
