Abstract
The higher-level graphics language LIG has now been operational for over two years. The language has proven to be easy to learn and easy to use, as attested by a number of programmers. Through its use, many improvement possibilities of the syntax and the supporting subprogram system have shown up. The experimental design of a higher-level special purpose programming language in terms of the linguistic characteristics of a language extension and its implementation with the aid of a compiler generator is discussed. A consideration of the data type GRAPHICAL, its properties and its manipulation as well as a description of the major parts of the language LIG follows, stressing its graphic capabilities and its features for handling interactive application programs. The paper concludes with remarks regarding an evaluation of the approach taken for the design and the language itself, together with a number of suggestions for improvements.Keywords
