Programming Languages: A general purpose graphic language
Helene E. Kulsrud · Communications of the ACM · 1968
Interactive use of computers with graphic terminals will permit many new problems to be solved using machines. In order to handle a variety of applications, it is expedient to develop a general purpose graphic language that is useful on a number of graphic devices. A system has been designed to produce such a language quickly and cheaply. A model graphic language which has been developed with the system is presented.
