An Approach to Understanding Program Comprehensibility Using Spatial Complexity, Concept Assignment and Typographical Style

process of comprehension more difficult. This was shown through an increase in the amount of information in the programs, as indicated by an increase in the number of concepts. In addition, by increasing the difficulty faced by a maintainer in acquiring the information contained within the programs, through an increase in the spatial complexity. Furthermore, our results also indicate that maintainers impose their own typographical style upon a program to aid their comprehension of that program.
