Viewing Variables in the Data View
The Data View is a powerful tool that can list any variable in your program, along with its current or previous value and other information. This helps you to monitor variables as your program executes:
*View changing values of variables.
*Drill down into the nested structures of compound variables (which you can also do in the Local Variables view)
*Add global variables to the Data View by directly typing them in.
*Add expressions involving your program data.
