<h2>Variables View </h2>
<p>The <b>Variables</b> view allows manipulation of the variables or variable hierarchy used in source code. For example, you can change the variable format, change a variables value, add watchpoints, and add global variables. </p>
<p>Figure 1 shows the Variables view with <b>Show Type Names</b> option enabled.</p>
