data segment
datastk  dw 3,-2,8,-8,67,-43,56,13,-9,-18,28,39
nums   dw $-datastk
sums dw ?
data ends

stack1 segment para stack 'stack1'
sd dw 20h dup(?)
stack1 ends

code segment
assume cs:code,ds:data,ss:stack1
being:  mov ax,data
        mov ds,ax

mov bx,offset datastk
mov cx,nums
mov dx,0
lop: add dx,[bx]
     inc bx
     loop lop
mov sums,dx

mov ah,4ch
 int 21h

code ends
end being
