Comments, with reply, on ´Structured flowcharts outperform pseudocode: an experimental comparison´ by D.A. Scanlan

The commenter maintains that what is being compared in the abovementioned article (see ibid., vol.6, no.5, p.28-36 (1989)) is the relative stability of flowcharts and pseudocode for the expression of a restricted aspect of actual programs, better isolated in the lab than in practice. He notes that the author avoids any loops in his three test algorithms. He points out that flowcharts require special output capabilities and an elaborate editor if they are to compare as a tool with pseudocode. The author responds that the commenter´s point about the lack of loops in the algorithms is well taken but that he chose algorithms very similar to those used in a study with which he wished to compare his results. He addresses other points made by the commenter, defending his own approach and conclusions.<>
