DOS Assembler

I'm using WinXP and i need to practice assembler. The catch is that i have to use the DOS interrupts (mainly INT 21). Do i have to install DOS or there is some way to emulate INT 21 in WinXP and to get the output on a console. Also what editor can i use.

Thanks!

Uhm, from what I know about running DOS/realmode programs written in assembler under Windows 2000/XP int 21h should work under XP without having to install or change anything. However 2000/XP restrict the access to certain other interrupts. (int 13h (BIOS disk services) for example)

BTW:
If you mean what editor you can use to write your code with, any editor that supports text documents should be fine. I often use Notepad.

Why not grab masm32 and write 32bit assembler code? You'll certianlly find it more useful then the old fashion. You can grab it at www.masm32.com
