   Uh well, my old machine with an XP was gathering dust anyway.   
      
   I copied a program that returns 2 and the geterror prog over to XP.   
      
   Then I first ran the program in DOSBox on my machine and then   
      
   debug geterror.com   
   u (which showed 0772:0104 as the address after the int 21h function 4D   
   g 0772:0104 (which showed AX=0002)   
      
   Next I ran the same thing on the XP machine in cmd   
      
   u (which showed 0d35:0104 as the address after the int 21h function 4D   
   g 0d35:0104 (which showed AX=0000)   
      
   But XP has cmd and not the dos command (which has no %errorlevel%, but   
   cmd uses   
      
   echo %errorlevel%   
      
   to show the return code and when I ran the program and then   
      
   echo %errorlevel% I got the 2, so that's what you should use.
