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 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
