TL;DR: The design and implementation of the interactive graphics language IGL is described, which not only allows the definition and display of line drawings but also has applications for manipulating, naming, identifying and interacting with such drawings.
Abstract: The design and implementation of the interactive graphics language IGL is described. This language not only allows the definition and display of line drawings but also has f u l l f a c i l i t i e s for manipulating, naming, identifying and interacting with such drawings. The language has been implemented as an extension to Fortran IV using the XPL compiler generator system. The experience gained so far i n the use of the language has already proven a number of advantages over present-day graphics systems. The language i s readily learned by users with previous high-level language experience. As no extensive testing and documentation i s necessary due to the readability of the program, the time required for the completion of a project i s greatly reduced.

TL;DR: A graphics package has been developed for use on Digital Equipment Corporation's GT40 and GT44 series of minicomputer-based graphics systems to allow almost complete control of the display processor by a programmer using the language BASIC.
Abstract: This article was prompted by the article written by Jon Meads in the Fall 1973 SIGGRAPH report. (1) A graphics package has been developed for use on Digital Equipment Corporation's GT40 and GT44 series of minicomputer-based graphics systems. Within the limitations of the machines, a package of graphics software was written to allow almost complete control of the display processor by a programmer using the language BASIC.
