  Assume there is a file called Myfile.

                              Myfile

  If you open the file for read "r" the file pointer fp 

  will be at the start of the file:

         fp ---------->

  If you open the file for append "a" the file pointer fp 

  will be at the end of the file ready to write ...

         fp ---------->

  If the existing file is opened for write "w", then effectively the 

  file is destroyed/rewritten.  A new file is created when opened for write!!

           /* Show wiping out of the file   */
