Advanced Monitoring Features › Conditional Breakpoints › Set Conditional Breakpoints

Set Conditional Breakpoints

The previous chapter showed how easy it is to set an unconditional breakpoint directly on your source listing. Just type u at the offset where you want the breakpoint.

To set a conditional breakpoint, begin by typing c to the left of the offset where you want the breakpoint, as shown next, and press Enter.

CA InterTest for CICS then displays the menu on which you define the condition. For example, the following screen sets the conditional breakpoint at the offset you identified in the previous screen only if TSSWITCH is equal to 3. The entries are as follows:

LEFT SIDE of  condition:
               Data Name  r13.tsswitch

               OPERATOR:  eq
RIGHT SIDE of condition:
                 Literal  3

To process the condition, press Enter. CA InterTest for CICS generates the command syntax for the conditional breakpoint, and returns you to the Source Listing screen.
