//  MODULE : Disk Animation header for the RCOS O/S simulator		  *
//  AUTHOR : Ron Chernich                                                 *
//  PURPOSE: Define absolute screen locations of elements comprising the  *
//	     disk drive graphic displays used by RCOS.  Where possible,   *
//	     all screen locations are relative to each other.		  *
//  HISTORY:                                                              *
