Abstract : GRIND (GRaphical INterpretive Display Language) is a language for drawing pictures and models on the PDP-9 Graphic 2 scope, which requires virtually no knowledge of computers and only an elementary knowledge of geometry. Programs are written using commands such as Line and Circle, and the results are instantly displayed on the scope. Mistakes are easily erased until a suitable final drawing is reached, which may then be saved on paper tape for future use. Since programming is done with specified lengths and positions, the resultant dimensions are exact and could therefore be readily used in subsequent computer analysis. A typed copy of commands is automatically printed enabling the user to reconstruct similar models or make changes with the minimum of effort. (Author)
