   It must be the command itself, or that which provides it, because   
   nothing else known that the   /X   in the string   'DIR /X >TEMP.TXT'   
   is in fact a switch.   
      
   Try it (at command prompt and in your program) with a "switch" that has   
   no known existence, such as /5 or /#, and with one that has "always"   
   existed, such as /W.   
      
   I suspect that the "DOS" at your command prompt (boot into a DOS-like   
   mode? MS-DOS prompt window?) is not actually the same as the "DOS" which   
   BP7 invokes.  See what string   GetEnv('comspec')   actually returns -   
   it *may* be a surprise.
