* 
*       UPDATE VIEW TABLE TO REFLECT KDVWLN DISPLAY STARTING FROM

* 
*     3.METHOD USED 
* 
*       FOR EACH TYPE OF STRUCTURE IN THE DISPLAY (APP, EST, LGL),
*       SET THE END INDEX TO THE MIN(REMAINING LINES IN VIEW WINDOW,

*       IF MORE LINES IN VIEW THEN SET NEXT START INDEX TO 1
*       ELSE SET NEXT START INDEX TO 0
*       IF STRUCTURE NOT BEING DISPLAYED, SET END INDEX TO 0.
