These things are dependent on the national standards
on the typewriter's keyboards. To make puter's
keyboard similar to typewriter's one, exist
keyboard drivers. My '2' key has standard '@'
on shift and red '"' for the Russian register,
'3' key has standard '#' on shift and red '/'
for Russian register and so on ...

The Russian keyboard driver takes the code of the 
pressed key and recodes this code or doesn't
recode it to get the ASCII or ANSI code of the letter,
which shape is on the pressed key, to put this
letter onto the screen. Drivers for Dos window
and Windows window are *different*.

There is a good program in euphoria/bin directory,
named key.ex. Run this programm and see the codes
*after your native keyboard driver*. Works fine
in Dos window.

But this simple program doesn't understand Russian 
at all under the Windows control. If I rename 
it as key.exw, then my Dos keyboard driver is blocked,
Windows keyboard driver doesn't work and I can 
input just ASCII.
 
But puts(1, "Pure Russian Text") works fine,
i.e. programmatically I can output normal Russian.
So, to have foreign languages on the input from
your keyboard under Windows you must use API.

These things are the great features of Bill's
products.
All too simple things become too complicated
just for understanding.

Pentium-IV crashed under Windows' '!' sign,
one bang and job done.
