8086 program to add 2 32-bit numbers

To write 8086 Assembly Language Program to add two 32-bit signed & unsigned number

code:

MOV AX,5000H ; Initialize DATA SEGMENT
MOV DS,AX ; to 5000H
MOV AX,[1000H] ; take lower 16-bit of NUM1 in AX
MOV BX,[2000H] ; take lower 16-bit of NUM2 in BX
ADD AX,BX ; AX = AX + BX
MOV [3000H],AX ; Store lower 16-bit result at NUM3
MOV AX,[1002H] ; take higher 16-bit of NUM1 in AX
MOV BX,[2002H] ; take higher 16-bit of NUM2 in BX
ADC AX,BX ; AX = AX + BX + CF (add with carry)
MOV [3002H],AX ; Store higher 16-bit result at NUM3
HLT ; Halt 8086
