Changing the program displayed in the disassembly view

You can use the SET QUALIFY command to change the program that is displayed in the disassembly view. Suppose you are debugging program ABC and you need to set a breakpoint in program BCD.

1. Enter the command SET QUALIFY CU BCD on the command line. z/OS® Debugger changes the Source window to display the disassembly instructions for program BCD.
2. Scroll through the Source window until you find the instruction where want to set a breakpoint.
3. To return to program ABC, at the point where the next instruction is to run, issue the SET QUALIFY RESET command.
