long interrupt_code is much larger than the 8bit ah register

btw: what are you doing? plain old dos 21h is decprecated since win95
most 16bit interrupt (int 0x10h, int 0x13...) procs don't work under win32

what do you want from dos? what are you trying todo?

I'm trying to read keyboard events through dos services.
If it's possible to access these services on the win32 platform let me know.

why do try to use dos interrupts - what speaks against phobos functions?

(i think) you can only use dos services (realmode emulation on top of 
win-api) within an real 16bit dos programm - and the D compiler/linker 
doesn't produce such exes

pure win32 programs (dmd compiled ones) cannot call dos interrupts 
neither can read ports or something like that

from which type of program you are trying to receive keystrokes?
window or console program?

Wow*. 

Dennis is right, using interrupts from user-land is *way* beyond depricated by
this point.  Under Windows, your only real alternative is to use the Win32 API.

You're going to want to google around some for this.  Its a little more involved
than I found a decent thread on another site that was started by someone who had
a similar question:

http://www.gidforums.com/t-2092.html

MSDN (http://msdn.microsoft.com) has some more info on the Win32 API, but its
pretty useless unless you already have an idea of what to look for.  Still, its
worth searching there for a good tutorial or two.

What you're looking for are the windows console API functions. Download 
microemacs from www.digitalmars.com for example code.

I tried it, and it compiles correctly. However, it won't run because 
Win32 programs cannot execute interrupt instructions.
