Display the Value of a Variable

When you are stopped at a breakpoint, you can request the display of the value of a variable directly from the source listing.

• To display its value where it is defined, type d to the left of the instruction defining it and press Enter, as shown in the next screen.
• To display the value of a variable where it is referenced, type d to the left of the instruction referencing it, place the cursor under any character in the variable, and press Enter.

The following screen shows how to display the value of a variable where it is defined.
