However, in the course of debugging a program written in a high-level language, the user is sometimes forced to try to understand the low-level implementation of his data structure, a task that may well be beyond his ability. In an attempt to obviate this problem a trace package has been written which allows a user at a TEKTRONIX Graphics Terminal to "see" arrays as two-dimensional data structures with rows and columns, and to examine interactively the contents of up to four arrays of any FORTRAN IV program while it is being executed. The package consists of a precompiler and a set of graphical routines, both designed to be fully portable. It has been used to debug programs with large arrays (which a standard line-by-line variables trace cannot comfortably handle). 1982-01-01T00:00:00Z https://ir.unisa.ac.za/handle/10500/24311 Reflections on the nature and future of computer science in Southern Africa Venter, BH Computer Science is a relatively recent scientific discipline. It has seen rapid growth and even more rapid change. Not surprisingly there is constant controversy among computer scientists about the nature of the discipline, and how best to pursue it. This article aims to stir up the controversy. The views expressed in it are personal, and the article is an adaptation of the author's inaugural address at Fort Hare University 1989-01-01T00:00:00Z https://ir.unisa.ac.za/handle/10500/24310 Software design to meet third world requirements: an experimental software engineering approach Machanick, Philip Appropriate technology refers to technology appropriate for use in less developed parts of the world, especially the Third World; this paper raises some problems in adapting a definition of appropriate technology to computer software. A partial solution, a strategy called experimental software engineering, is introduced. The potential of this solution is demonstrated by a case study, in which software for medical education is developed. The result is a clearer understanding of both appropriate technology and design of software for usability. 1989-01-01T00:00:00Z
