Addition problem

[RedDevil]

Hi guys.

I've got a problem in my addition for my assembly. i'll post the code here

		CheckBit1 proc

			mov dl,hammingNum[2] ;lets say [2] stored in side is 1
			add dl,hammingNum[4] ;lets say [4] stored in side is 1 also

			mov hammingNum[0],dl ;store the 1+1 =2 to [0]

			;=====REMOVE WHEN NOT NEEDED=====
			
			call ClearScreen

			mov dl,hammingNum[0]
            mov ah,02h ;display the output here
            int 21h
			ret

		CheckBit1 endp

when i tried to add what's in [2] and [4], the output i got is 'b'! The output i want is suppose to be 1+1 = 2 ! not 1+1 = 11 where in ascii value is 'b'. How do i solve this problem? Please do help me! Thanks!

hi, this is a small example how to add from memory address.
u could use the debug program in command prompt to try.

-a
0AE6:0100 mov ax,1
0AE6:0103 mov [0400],ax
0AE6:0106 mov bx,2
0AE6:0109 mov [0402],bx
0AE6:010D mov dl,[0400]
0AE6:0111 add dl,[0402]
0AE6:0115
