Lets get in to a small program, first a basic example:


10 LET A=65536
20 POKE a,128

THE EQUIVALENT CODE MAY DIFFER ON MACHINES (OUR COMPUTER
IS MADE UP TO EASE THE EXPLANATION AND UNDERSTANDING)


A.  LD.B 128 or $80,D0      OR  MOVE.B 128 or $80,D0

B.  LD.W 65536 or $FFFF,A0  OR  MOVE.W 65536 or $FFFF,A0

C.  LD D0,(A0)              OR  MOVE D0,(A0)



A . Loads/moves (LM) a byte length number, in this case
the number 128 into     data register D0

B . This means LM the number 65536 (a word long number )
into the address     register A0

C . This means load the number in the data register d0
(which is 128) into the location pointed to by the address
