DTIC ADA016811: PYGMALION: A Creative Programming Environment

PYGMALION is a two-dimensional, visual programming system implemented on an interactive computer with graphics display. Communication between human being and computer is by means of visual entities called icons, subsuming the notions of variable, reference, data structure, function and picture. The heart of the system is an interactive remembering editor for icons, which executes and (Optionally) saves operations for later reexecution. The display screen is viewed as a document to be edited. Programming consists of recreating a sequence of display frames, the last of which contains the desired information. Display frames are modified by editing operations.
