CODE SEGMENT

ASSUME CS:CODE, DS:DATA

START:MOV AX, DATA; Initialise data segment

MOV DS, AX; register using AX

MOV AL, NUM1; Bring the first number in AL

ADD AL, NUM2; Add the 2nd

Number to AL

MOV RESULT, AL; Store the result

RCL AL, 01; rotate carry into Least Significant Bit (LSB)

AND AL, 00000001B; Mask out all but LSB

MOV CARRY, AL; Store the carry

MOV AX, 4C00h; Terminate to DOS

INT 21h

CODE ENDS

END START
