You can change the order in which
functions on the call stack are displayed in the Call Stack
window -- with the most recent entry at the top, or at the
bottom. You can have the window display the most recently called
routine at the top, and the outermost calling routine (usually
the main program) at the bottom. If you click on the
button, the order is reversed.
To change the default growth direction, select Options->Display style and choose the appropriate growth direction from the dialog.
