Can anyone tell me how to read the state of arrow and shift keys in a 32-bit

trying to write a text-mode text editor and have the following problem. When I
compile 16-bit dos apps with -mld, I can detect shift and arrow keys with
getch() and _bios_keybrd etc but then can't access more than 64k of memory. When
I compile normal 32 bit apps I have no memory problems but then can't detect
arrow keys etc with getch() and _bios_keybrd is unavailable.

I've tried looking at the X32 extender but it is beyond me. Is there an easier
option?

The source to MicroEmacs (from www.digitalmars.com) it has code in it to
read the keyboard from DOS, DOS32, and Win32.
