Contains the source for the routine associated with the selected stack frame. The arrow in the left margin of the Source Pane indicates the location of the PC for that stack frame.

To set breakpoints in the process, click on the line number. A “stop sign” icon appears under the cursor. To clear a breakpoint, place your mouse over the stop sign and click on it again. To set or alter an action point’s settings, select the line and then select the Action Point > Properties command. (Right-clicking the line brings up a popup menu. You can select Properties from this menu.) Note that breakpoints apply to all threads in the process.

To view the source for a function or the contents for a variable whose name appears in the Source Pane, double-click on it or, after selecting it, use the View > Dive command. If you click on a function, TotalView shows the function in the source pane by replacing the information that was being shown. You can return the display to how it was previously by selecting the < indicator located to the right of the source pane.

If you click on a variable, information for the variable appears in a separate window.
