Interface Problems in a Multipurpose Tester

This paper discusses an approach to the analysis of existing support systems and provides a guide for the planning of new systems. An analysis of the basic elements of a support system is presented and, having defined a set of basic elements for a support system, this paper then applies these elements to the special problems of a multipurpose tester. Several examples of the interface element are presented, each example providing a different approach to the solution of the interface problem, and the relative merits of each solution are discussed.
