 ;	Suppose your  program  cartridge  is  32k  bytes
 ;	long (4000H..0BFFFH).   You  set the ID at 4000H
 ;	and 4001H and the execution start address within
 ;	page 1   (4000H..7FFFH).    MSX  passes  control
 ;	to this address so the  part  which  resides  in
 ;	page 2  is  not  yet enabled at this point.  You
 ;	have to know where  you  are  (in  what  primary
 ;	slot. in  what  secondary  slot)  and enable the
 ;	part at page 2.  Below  is  the  sample  program
 ;	to do this.
