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 a d to the left of the statement defining it and press Enter, as shown in the following screen.

To display the value of a variable where it is referenced, type a d to the left of the statement referencing it, place the cursor under any character in the variable, and press Enter.

CA InterTest for CICS responds by displaying the contents of the variable in structured format, as shown next.
