Assembler mov issue
I have the next code:
mov ax,@开发者_StackOverflow社区data
mov ds,ax
Why I can not write just like this?
mov ds,@data
All source:
.MODEL small
.STACK 100h
.DATA
HelloMessage DB 'Hello, world',13,10,'$'
.CODE
.startup
mov ax,@data
mov ds,ax
mov ah,9
mov dx,OFFSET HelloMessage
int 21h
mov ah,4ch
int 21h
END
Thank you!
You can't move directly @data in ds because you can't assign directly a segment to ds. You are allowed to move a register with the value of the segment you want to move in ds.
