What You Can Do When Your Program Is Stopped

Once a program is stopped, you can use the CA InterTest for CICS testing and debugging facilities to do the following tasks:

• Examine the source listing
• Examine and modify main and auxiliary storage to detect and correct errors
• Set and remove breakpoints
• Examine a program's backtrace, or execution path
• Keep variables in a Keep window to observe changes in their values
• Abend your task with or without a dump
• Go around a problem by resuming program execution from a location other than the one at which the program is currently stopped
• Execute the program in single‑step mode; that is, the program executes one verb and then stops

  Note: All of the previous activities are detailed in the next chapter.

Now we will demonstrate how easy it is to control program execution by setting an unconditional breakpoint.
