Pointer Incrementing Warning

Hi Friends,
I'm Currently working on C51v6.02 developed by Keil, I'm facing a problem with the compiler when I compile a similar code like this

main()
{
   char xdata *Data_Ptr = 0x0000; /* Pointer to the 0x000 location */

   while(some loop)
   *Data_Ptr++; /* Points to the next data location on the RAM-- here 0x0001 */
}

when I compile this it gives the following warning message,

 .\FILENAME(LINENUMBER): warning C275: FILENAME: expression with possibly no effect 

Is there any way to avoid this warning message?? Thank you,

With Regards,
Yaswanth
