   I have created this linked list at the end of the file (in data seg):

        head->[111,21,31]->[222,22,32]->[333,23,33]->
              ->[444,24,34]->[555,25,35]

   The List object structure is as follows:     

                     int value1;     // Offset = 0
		     short value2;   // Offset = 4
		     short value3;   // Offset = 6
		     List  next;     // Offset = 8
