*     Course Number    :                  CIS-112                                 *
*     Assignment       :                  Project # 4                             *
*     Due Date         :                  May 8/9, 2002                           *

*     Instructor       :                  Jim Chaires                             *
*     Input            :                  Disk File - "personel.bin"              *
*     Output           :                  Screen/Printer                          *
*     Program Objective:    Program # 4 takes program # 3 and uses objects and    *
*                       classes instead of structures. As in program #3, an array *
*                       is built, the array is sorted on name and employees who   *
*                       make more than $41,000 are printed.                       *
