I can't vouch for Win2k. Under Win98, I have a program that does

   procedure Create_File_List is
   -- Use DOS dir command to create list of signature-file names
      Arg     : Os_Lib.Argument_List_Access;
      Success : Boolean;
   begin -- Create_File_List
      Arg := Os_Lib.Argument_String_To_List ("/c dir/-p/b signature?? >
" &                                              File_List_Name);
      
      Ensure_Success : loop
         Os_Lib.Spawn (Program_Name => "command", Args => Arg.all,
                       Success => Success);
         
         exit Ensure_Success when Success;
      end loop Ensure_Success;
   end Create_File_List;
