*     A. LIM.    81/10/20.
* 
*     THE FUNCTION OF THE MAIN PROGRAM IS TO LOAD AND EXECUTE THE 
*     INITIALIZATION OVERLAY AND TO BE THE SKELETON FOR THE MAIN (0,0)
*     OVERLAY.

*     PRGM CS 
* 
*     ENTRY   NONE. 
* 
*     EXIT    THERE IS NO EXIT IN THE USUAL SENSE.  THE MAIN PROGRAM
*             TRANSFERS CONTROL TO THE INITIALIZATION OVERLAY, WHICH, 
*             WHEN COMPLETE, TRANSFERS CONTROL TO THE PROGRAM EXECUTION 
*             SEQUENCER (*SSSPES*), WHICH NEVER RETURNS.
