//  MODULE : ANIM - Animator Device Driver for the RCOS OS simulator    *
//  AUTHOR : Ron Chernich                                               *
//  PURPOSE: Module to perform all screen animation operations and re-  *
//           draw of switched displays.                                 *
//  HISTORY:                                                            *

//   18-AUG-94  static func of module made private member               *
//   15-MAR-95  Modified to accomodate improved user tty encapsulation  *
//   22-MAR-95  (Happy Birthday, Ron!) No of terminals made dynamic     *
