CAST Complexity Metrics
The CAST Quality Model contains various metrics that are classed as "Complexity metrics", i.e. metrics that measure the complexity of artifacts in an application. This page contains a basic description of the mechanisms used to determine the complexity of a given artifact.
CAST Complexity Metrics
CAST provides data for the following "Complexity metrics":
...
Each Complexity metric takes into account different statements - these are listed below.

For all the metrics listed below, the program or sub-program entry point is counted as one1. As a consequence, all the metrics below will have a minimum value of one1 (even if the object contains no code). When the minimum value is assigned to an object, an INFO message is listed in the analysis log, for example:

Cyclomatic Complexity
To compute this metric, a counter is incremented by one each time one of the following statements is encountered:
...
