    12 <p>  Use <em>watchpoints</em> (sometimes referred to as access breakpoints) to halt program execution when a specific global location is accessed. After you set a watchpoint at a key point in memory, you can halt program execution whenever that point in memory is written to or read from. You can then examine the call chain, check register and variable values, and step through your code. You can also change values and alter the flow of normal program execution.</p>
