This paper shows the reader:

• The usage of certain metrics to assert program quality.

• :1DThe distinction btween quality and structuredness of software.

• thorough study of rules and their usage. The conlusion is: metrics ae relatively insensitive to program structures, as one does not use McCabe’s type of metrics as unidimensional.

• combinational approach is necessary, but which is probably difficult to quantify. Indeed, how will one measure style and understandability for the bunch of programming languages?

This article is very legible and deserves attention from anyone who is involved with topics like productivity, quality, and maintenance of software products.
