Statement: Calculate the sum of series of odd numbers from the list of numbers. The length of the list is in memory location 2200H and the series itself begins from memory location 2201H. Assume the sum to be 16-bit. Store the sum at memory locations 2300H and 2301H.
| Sample problem 1: 2200H = 4H 2201H= 9AH 2202H= 52H 2203H= 89H 2204H= 3FH Result = 89H + 3FH = C8H 2300H= H Lower byte 2301H = H Higher byte

Source program :
- LDA 2200H
- MOV C, A : Initialize counter
- LXI H, 2201H : Initialize pointer
- MVI E, 00 : Sum low = 0
- MOV D, E : Sum high = 0
- BACK: MOV A, M : Get the number
- ANI 0lH : Mask Bit 1 to Bit7
- JZ SKIP : Don't add if number is even
- MOV A, E : Get the lower byte of sum
- ADD M : Sum = sum + data
- MOV E, A : Store result in E register
- JNC SKIP
- INR D : Add carry to MSB of SUM
- SKIP: INX H : Increment pointer
