Quick-start Tutorial

Using the call stack

The Call Stack pane enables you to follow the flow of your program by examining the

current status of functions and variables. This pane shows you the path that leads from

the main entry point to the currently executing function.

To monitor your execution path:

1. Select View → Pane Views → Call Stack from the default Code window to

display the Call Stack pane.

2. Select File → Reload Image to Target to reload the image.

3. Click the Go button on the Actions toolbar to execute the image. Enter a large

number of runs, for example

50000

4. Click Stop Execution to stop the program before it finishes.

The Call Stack tab, in the Call Stack pane, displays details of the functions

currently on the stack and awaiting execution.

5. Right-click on an entry in the Call Stack pane, to see the Function context menu.

This menu enables you to carry out operations on the chosen function in the stack,

for example to scope to that function.

6. Click on the Locals tab in the Call Stack pane. This displays a list of the variables

that are local to the current function, shown in the example in Figure4-11.

Figure4-11 Local variables in the Call Stack pane

If a variable is a structure or an array, a plus sign is added to the entry in the Call

Stack pane. You can click on this to expand the variable to see all elements of the

structure or array.

7. Right-click on an entry in the Locals tab, to see the Varia ble s context menu.

8. Click on the Statics tab, to see non-local variables, that is module statics.
