Breakpoint Activities

After a program is stopped, you can use the 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 the Watch Data view 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
