MDBG

If you are using z/OS® XL C/C++, Version 1.10 or later, you can indicate that z/OS Debugger always searches for .mdbg files to retrieve the source and debug information by using the MDBG command.

The following diagram describes the syntax of the MDBG command:

YES
Indicates that z/OS Debugger searches for .mdbg files.
NO
Indicates that z/OS Debugger does not search for .mdbg files.
When you set MDBG to YES, z/OS Debugger retrieves the debug information from an .mdbg file and does not try to find the debug information from the following sources, even if they exist:
  • a .dbg file
  • if the program was compiled with the ISD compiler option, the object
If you do not specify MDBG or set it to NO, z/OS Debugger retrieves the debug information from either the .dbg file or, if the program was compiled with the ISD compiler option, the object.
