You can reach this option through the ‘Evaluate symbol’ option of the debugger menu. This option leads to a dialog box that prompts you for an expression to evaluate and displays the results in a list box, below the input combo box.
It is simple to use: Type the expression to evaluate in the combo box line and the result is displayed below. In principle, all symbols in your program should be available for display. In practice, there could be some problems. See below for further information.
