Variable in section .data is initialized to wrong value

[Abod-Shashtari]

CODE:

.model small
.8086
.data
v1 dw 4
.code
mov ax,0
mov ax,v1
.exit
end

Problem: AX value is not 4
NOTES: Assembler => MASM

I fix it by adding

mov ax,@data
mov ds,ax

The code will be like this:

.model small
.data
v1 dw 4
.code
mov ax,@data
mov ds,ax

mov ax,0
mov ax,v1

.exit
end
