Portability Evaluation of AFIT-GKS (Air Force Inst. of Tech. - Graphical Kernel System). An Ada Implementation of the Graphical Kernel System

摘要

The purposes of this thesis were to develop an Ada implementation of the American National Standard Institute's new standard for computer graphics, the Graphical Kernel System (GKS), and to have it operating on an Air Force Institute of Technology (AFIT) computer system. The basis for this implementation was AFIT GKS, a subset of GKS designed and coded by 2Lt R. Scott Ruegg on the Aeronautical System Division's Rolm Data General Computer for his 1984 AFIT thesis, AFIT GKS -- A GKS Implementation in the Ada Programming Language. It seemed possible to install AFIT GKS on an AFIT computer, to improve AFIT GKS by modifying it to address more capable display terminals, and to initiate testing and evaluation of AFIT GKS in accordance with the methods and guidelines currently under study by the National Bureau of Standards.
