This must be a really dumb question, but I don't seem to be able to figure out how to obtain a listing file. I just downloaded open-watcom-c-win32-1.7a.exe and installed it without any difficulty. It assembles my source file and I can link with wlink. It all works perfectly. After more than 2 years, I am able to duplicate the DLL file that I am using and which I want to modify. But wasm /h command does not even mention anything about a listing file! Is there any way that I can obtain a listing file of the assembled source code? Thus far, WatCom has the only assembler / linker pair that I have found which can duplicate the DLL that I am using. So shifting to a different assembler may not be useful. Does WatCom have another EXE file that I am missing that is used to produce a listing of the assembled source code? Also, it would be helpful to have a link map, although right now I probably would not know what to do with one. Sincerely yours, Jerome Fine
