**    CSLEVT - EVENT PROCESSING OVERLAY.
* 
*     A. LIM     82/06/14.
* 
*     THE FUNCTION OF THIS PROGRAM IS TO BUILD THE SKELETON OF THE
*     EVENT PROCESSING OVERLAY (01,00) AND TRANSFER CONTROL TO THE
*     APPROPRIATE ENTRY POINT (*OVENUM* IN COMMON BLOCK IN TEXTSS). 
*     UPON EXIT, CONTROL TRANSFERS TO SERVICE AND SCHEDULOR THROUGH 
*     *SSORTN*. 
* 
*     PRGM CSLEVT 
* 
*     ENTRY    NEXT OVERLAY ENTRY POINT NUMBER *OVENUM* TO EXECUTE. 
* 
*     EXIT     OVERLAY ENTRY POINT NUMBER *OVENUM* EXECUTED, AND
*              CONTROL RETURNS TO SERVICE AND SCHEDULOR THROUGH 
*              *SSORTN*.
* 
*     METHOD   *OVENUM* IS USED IN A SWITCH ITEM TO SWITCH TO THE 
*              APPROPRIATE ENTRY POINT TO EXECUTE.  UPON RETURNING
*              FROM THE PROC, CONTROL RETURNS TO SERVICE AND
*              SCHEDULOR THROUGH *SSORTN*.
