Im new so I really need help with Masm and all its ways so I got a code for assembly. Can anyone tell me whats wrong with it? It keeps giving me error. Its from a tutorial to add.
.model small
.stack
.data
message db "Hello world, I'm learning Assembly !!!", "$"
.code
main proc
mov ax,seg message
mov ds,ax
mov ah,09
lea dx,message
int 21h
mov ax,4c00h
int 21h
main endp
end main
Could be your boilerplate stuff, you have no org 100h

.model small
.stack 100h
.data
message db "Hello World", 13, 10, "$"
.code
start:
mov ax, @data
mov ds, ax
mov dx, offset message ; copy address of message to dx
mov ah, 9h ; subprogram for string output
int 21h ; call ms-dos to display string
mov ax, 4c00h
int 21h
end start

Ajax,
Your code, as posted, assembles, links, and runs OK. I have no idea what you may be doing wrong, but this post (http://www.masm32.com/board/index.php?topic=7245.msg53711#msg53711) may provide a solution.
Okay I changed it a little bit but I get the error saying that message in line 9 is an unidentified symbol.
.model small
.stack 200h
.data
message db "Hello world, I'm learning Assembly !!!", "$"
.code
_main proc
mov ax,seg message
mov ds,ax
mov ah,09
lea dx,message
int 21h
mov ax,4c00h
int 21h
_main endp
end _main
Using MASM and the 16-bit linker, the code copied directly from your last post assembles, links, and runs OK.

I dont know but could it be the IDE im using? Im using MASM32 IDE and something from Microsoft, LINK its a Segmented Executable Linker. Can some one tell me if thats right.
Ok, that explains the error you are getting on line 9, apparently being caused by the SEG operator. For information see this and following posts:

Sry to say but that stuff confuses me so just in general what should I do?
