The call stack helps in showing the program flow. It shows the list of procedures that are being called at this moment, in reverse order. The call stack window can be shown using the ”Debug—Call Stack” menu. It will show the address or procedure name of all currently active procedures with their filename and addresses. If parameters were passed they will be shown as well. The call stack is shown in figure (6.15).
By pressing the space bar in the call stack window, the line corresponding to the call will be highlighted in the edit window.
