/CO[[DEVIEW]]
The /CO option adds Microsoft Symbolic Debugging Information to the executable file. Debugging information can be used with the Microsoft CodeView debugger. If the object files do not contain debugging information (that is, if they were not compiled or assembled using either /Zi or /Zd), this option places only public symbols in the executable file.
You can run the resulting executable file outside CodeView; the debugging data in the file is ignored. However, it increases file size. You should link a separate release version without the /CO option after the program has been debugged.
When /CO is used with the /TINY option, debugging information is put in a separate file with the same base name as the .COM file and with the .DBG extension.
The /CO option is not compatible with the /EXEPACK option for DOS executable files.
