When the debugging session cannot begin, the debugger will display an error message at invocation. This indicates that a filename
required by CodeWatch is an error because one or more of the following is true:
- It does not exist or is not in the current directory.
- The program file specified to be debugged is not an executable file.
- None of the program modules in the program file was generated from a compilation using the -deb option.
- The necessary debugger information files cannot be found in any of the specified or default directories.
