   What's wrong with this source code? It calls "GetCommandLine"   
   to get a pointer to the command line, then skips the program   
   name to get the pointer to the new title string given on   
   the command line. Then it gets the handle to the console   
   window (GetConsoleWindow), sets the new title (SetWindowTextA)   
   and terminates the program (ExitProcess). Anything else you see   
   in the list file is normally generated by the assembler and linker   
   (but if I want a small exe file to include it in a batch program,   
   I do it by hand). You can also write it as a two line C program, but   
   don't expect to get a 1 kByte binary.
