Theory

Instruction Mnemonic	Operand	Comments
LXI	H,8100	Load the contents of 8100 in H-L pair registers
LXI	D,8200	Load the contents of 8200 in DE
MVI	C,04	Store size of list in register C
LDAX	D	Load contents of register D to Accumulator
ADD	M	Add contents of memory i.e., HL to Accumulator and store in accumulator
MOV	M,A	Move contents of accumulator to memory i.e., HL pair
INX	H	Increment HL pair by 1(8100 to 8101)
INX	D	Increment DE by 1
		(8200 to 8201)
