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 increases amazingly fast. But the developement of high-level programming languages, which include standard constructs for processing graphical informations, is far from where it could be. A good system should provide intelligible constructs, easy to learn and similar to usual programming, so that the programmer can fully concentrate upon the design of his pictures. For these purposes PASCAL/Graph*) was designed and implemented.10.2312/eg.19811014
