The high-level graphics programming language PASCAL/Graph

A high-level programming language like PASCAL offers data types, variables, constants and operators, with which the programmer can represent the actual world as a model inside the computer. The world of numbers and text has been represented in the computer for many years by various kinds of variables. The importance of computer graphics is increasing extremely fast. But the development of high-level programming languages, which include standard constructs for processing graphical informations, is far from where it could be. A good system should be based on understandable concepts, easy to learn and similar to normal programming, so that the programmer can fully concentrate upon the design of his pictures[1–4]. For these purposes PASCAL/Graph³ was designed and implemented[5–8].
