write a program that adds three 16-bit
integers using only registers. Insert a call DumpRegs
statement to display the register values.

Solution

Here we are storing three values in value1, value2 and in value3 and summation of three values is stored in result.

.data
;Setting the valiarbles
value1 DWORD 20000h
value2 DWORD 30000h
value3 DWORD 50000h
result DWORD ?

.code
main PROC
mov ax,@data
mov ds,ax
mov eax,value1 ; get first value
add eax,value2 ; adds second value
add eax,value3 ; adds third value
mov result,eax ; store the result
call DumpRegs ; display registers
exit

main ENDP
