Find the memory location of variables using assembly language

Question

Hello m new to assembly language. I am trying to get the memory location for variables m using DOSBOX and MASM compilor Here is the code

     .model small
   .stack 100H
 .data
   VARA BYTE 10   ;address is DS:xxxx
 VARB BYTE 0BH  ;address is DS:xxxx+1
 VARC WORD ?
   VARD SBYTE ?
   VARE DWORD ? 
   ARR BYTE 20 DUP(?)
  VARF SWORD 010B
  ARRB WORD 10 DUP(?)
  VARZ BYTE 0
 .CODE
  MAIN PROC
    mov ax,@data
mov ds,ax
mov ax,offset VARA
mov ah,09
int 21h

mov ax,offset VARB
mov ah,09
int 21h


    mov ax,offset VARC
mov ah,09
int 21h

    mov ax,offset VARD
mov ah,09
int 21h


    mov ax,offset VARE
mov ah,09
int 21h


mov ax,offset ARR
mov ah,09
int 21h


    mov ax,offset VARF
mov ah,09
int 21h

    mov ax,offset ARRB
mov ah,09
int 21h

mov ax,offset VARZ
mov ah,09
int 21h


mov ah,4ch
int 21h
main endp
end main

How can i find the memory address for all these variables? U can see the error in the image

Answer 1

Use the OFFSET modifier, eg:

mov ax, OFFSET VARA

to load the address of VARA into the ax register. You can also use the LEA instruction to achieve the same thing:

lea ax, VARA
