stack segment para stack
db 20h dup(0)
stack ends

code segment
assume ss:stack,cs:code,ds:data
start:
mov ax,data
mov ds,ax
lea dx,Msg1
mov ah,09h
int 21h
xor bx,bx
xor cx,cx
execute:
mov ah,01h
int 21h
mov cl,10
cmp al,0dh
jz exit
sub al,30h
mov dl,al
mov ax,bx
mul cl
mov bx,ax
add bx,dx
jmp execute
exit:
mov ah,4ch
int 21h

code ends
end start
