Macro-Graphics for the 1500 System.
McGinnis, N. P.
The 1500 System allows only a restricted number of dictionary-graphic areas in core. To solve the practical problems thereof, the Division of Educational Research Services at the University of Alberta attempted to use a universal dot dictionary, but this solution was not feasible for two reasons: Coursewriter input cannot exceed 250 characters per statement and a dot dictionary is a combersome solution for authors. An emphasis therefore was put on developing the Macro-Graphic System. This system has two most important features. They are: 1) any graphic display can be set up on the CRT without the need for dictionary core-areas as set up in the 1500 System; 2) it is easier for an author to learn to use this system than it is for him to master the existing 1500 dictionary graphic system. In addition, more courses can be supported simultaneously on this system. A Coursewriter course, called DRAW, along with two special purpose functions DRAWX and DRAWY have been developed to prepare macro-graphics. (CH)
