Program complexity and programming style

In a recent paper⁽¹⁾ the author has presented evidence that, contrary to several studies in the literature, certain software complexity metrics are not consistently sensitive to the application of program style rules. In the present paper, these results are summarized and extended to two additional metrics. The new results indicate both that current complexity metrics are improper indices of program quality, as measured by style, and that many commonly used style rules do not address questions of minimizing interprocedural information flow complexity.
