Use this option to specify the number of columns that you want to display in the memory window. A Prompt dialog is displayed for you to enter an integer in the range 1 to 32 to specify the number of columns, or 0 to indicate that you want RealView Debugger to set the number of columns automatically. If you do not specify a number of columns, RealView Debugger displays as many pairs of columns as it can in the window.
