Tracing Through Code
One of the most useful debugging strategies at your disposal is the ability to trace through code, see each line of code as it executes, and check the values of all variables, properties, and environment settings.

Start a debugging session.
If no program is open in the Trace window, choose Do from the Debug menu.
Choose Step Into from the Debug menu or click the Step Into toolbar button.
An arrow in the gray area to the left of the code indicates the next line to execute.

From the Debug menu, choose Fix.
When you choose Fix from the Debug menu, program execution is canceled and the code editor is opened to the location of the cursor in the Trace window.
