I'm very beginner in Assembly, And I'm trying to write a program that find the square root of a perfect square root number . my variables does not change when I move something immediately, check variables Box in screen shots

my code:

.data
number dw ? 
result dw ?
.code
    main proc
         
        mov [number],400
        mov cx,0
        
        calc:
        mov ax,cx
        mul cx
        cmp ax,[number]
        jz save
        inc cx
        jmp calc
        
        
        
        save:
        mov [7102],cx
        
        
        
        
        
        hlt
       
    endp
    end main

CodePudding user response：

I accidentally found the answers to my question, in order to see the changes of the variables, you have to save your data segment address in the DS register, for this you can use the following code!

mov AX,[DATA]  ;[DATA] means the address of data segment like &DATA in C 
mov DS,AX

Note that you can not directly store the data segment address in the DS register, because the DS register does not have direct access to memory!
