Hi ada activists, We are currently performing a code walkthrought (ada source code of course). In the checklist we have an entry for maintainability along with others like readability, conformance with coding standard, data flow errors, testability, etc. We found some problems to decide whether a compilation unit passes or fails on the maintainability topic. One option could be to evaluate the complexity of the code using Mccabe, Haltstead, or/and Harrison figures. In this way the problem is the establishment of the valid range for these figures. If someone can enlighten me or provide any useful information, thanks a lot. Angel Fernández Guerra.
