After you have launched a debug session, you can modify or add to the source location list by completing these steps:
If your program was not compiled with -qfullpath, the source has moved, or you are debugging on a system other than the one on which your program was built, the debugger may locate the incorrect source for the current stack frame. If this happens, you can change the text file that opens in the editor:
When source cannot be found, the editor opens without source.
To open a Disassembly view of the source, click Show Disassembly.
