Explain Debug monitors.
Debug monitors give debugging support for a program. A debug monitor executes the program being debugged in its own control thereby giving execution efficiency throughout debugging. There are debug monitors which are language independent and can handle programs written in several languages. For illustration-DEC-10.
Debug monitor give the following facilities for dynamic debugging:
1. Setting breakpoints into the program
2. Initiating a debug conversation while control reaches a breakpoint.
3. Displaying variable's values
4. Assigning new values to variables.
5. Testing in defined assertions and predicates including program variables.
