Someone sent me mail, asking for a demo for reading the key.
Following are a short examples in C.  For simplicity I presume that 
'getchar' returns 8 bit clean character from the keyboard.

Here is a short code fragment in C to read a key from the keyboard:
(this is the way it *should* be done)

int read_a_key_from_keyboard()
{
	return (getchar());	/* this is ok.  It leaves the 8th bit alone */
}


Now, here is a fragment that could fit Aled.  I am sorry to say that this type
of coding is *much* too *much* common:
(this is the way it *SHOULD NOT* be done.)

int read_a_key_from_keyboard_the_way_the_americans_do_it_bad()
{
	return (getchar() & 0x7f);	/* this one is not ok.  It masks the */
					/* 8th bit off.  USELESS to us       */
					/* Icelanders!!!!!!!!                */
}


(frisk posted a good list of what should be done for foreign support.)  I don't
know the article number, but this, at least, is the beginning of programming
for foreign countries.
