way to compile assembler code

Question

just started learning Assembler in school, and want to ask how to compile this code:

stek Segment Stack
DB 256 DUP(?)
stek ENDS

CR EQU 13
EF EQU 10

Duom SEGMENT
pranesimas DB 'Hello Word', CR,EF
           DB 'Made By Edgar' $
Duom ENDS


prog SEGMENT

ASSUME CS:programa,ds:Duomenis,ss:stekas

START:
        MOV ax,duomenis
        MOV ds,ax

        MOV ah,09
        LEA dx,Pranesimas
        INT 21h


        MOV ah,4ch
Prog ENDS

END START

on windows 7 x64

because in school we have Xp x32, the way we compile in school does not work on x64 windows.

just it writes "... is not compatible with this version of windows..." — Edgar, Sep 23 '12 at 15:31
@JensBjörnhager The program he is trying to assemble is a 16 bit DOS program that afaik won't run on anything newer than XP without something like [DOSBox](http://www.dosbox.com/information.php?page=0) — Joachim Isaksson, Sep 23 '12 at 15:35
Please, we do not compile Assembly code, we Assemble and optionally link. — Gunner, Sep 23 '12 at 22:20

The newer versions of Windows have dropped the 16-bit support that used to be there in XP, so to compile the program (a 16 bit DOS program), you'll need to install DOSBox, Bochs or similar emulator.

They will emulate the 16-bit environment so you should be able to run DOS with both the assembler and resulting code on your 64-bit Windows (or Mac/Linux machine for that matter)
