| Reports any uses of variables which are known to be constant. This | |
| is the case if the (read) use of the variable is surrounded by an | |
| <b>if</b> or <b>while</b> | |
| statement with an == condition which compares the variable with a constant. In such | |
| a case the use | |
| of a variable which is known to be constant can be replaced with the actual constant. | |
