This report describes a high level programming language implemented for the Shaded Graphic System at Case Western Reserve University. It consists of a complete implementation, for the PDP-11, of Algol-60 with the addition of string variables, I/O facilities, and extensions for handling shaded graphic images. The primary purpose of this work was to facilitate the use of a custom-built system which can produce shaded perspective images in real-time.
