What You Can Do When Your Program Is Stopped

Once a program is stopped, you can use the CA InterTest 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 data items 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 these activities are described in detail in the next chapter.

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