During procedure execution, the Debugger window displays the listing of the procedure at each breakpoint or stopping point in its execution. A pointer always indicates the next line to execute. At any stopping point, you can display the listing for any procedure file using File > Open. This provides a convenient way to set breakpoints for any procedure in your environment, whether or not it is called from the procedure you are running.

You can examine and navigate the procedure call stack using the ABL stack trace pane. This allows you to examine the current code path back and forth through the active series of procedure calls and triggers starting from the current stopping point.
