Sun Studio 12: C User's Guide Changing the Value of a Variable

At times, you may want to see how a proposed change affects your code.

Suppose you want to change the value of a variable or preprocessor symbol. Before doing so, use the first menu item, Find this C symbol, to obtain a list of references that are affected. Then use the editor to examine each one. This step helps you predict the overall effects of your proposed change. Later, you can use cscope in the same way to verify that your changes have been made.
