Abstract: Claims for the virtues of visual programming languages have generally been strong, simple-minded statements that visual programs are inherently better than textual ones. They have paid scant attention to previous empirical literature showing difficulties in comprehending visual programs. This paper reports comparisons between the comprehensibility of textual and visual programs, drawing on the methods developed by Green (1977) for comparing detailed comprehensibility of conditional structures....
