Available in PDF, EPUB and Kindle. Book excerpt: During the spring of 1973, the Graphics Compatibility System developed by ISD was nearing the final stages of debugging and showed great promise. One persistent problem, however, was poor response time during a GCS execution due to the cumbersome size of the GCS library. To meet this problem, a pre-overlaid version of the GCS library and a run-time executive to coordinate swapping has been developed. Primary goals of this effort were: (1) the entire GCS library must be available; (2) the core requirements should be modest; (3) the user need not specify any explicit overlaying; and (4) the user must be able to write, debug, and run his routine under time-sharing. The balance of this paper describes this technique. Section I discusses the concepts involved. Section II describes the GCS implementation in detail.
