Well, the get_key() routine does the exact same thing as Inkey$ (most BASIC
routines have Euphoria equivalents). If you have a file and you want to have
stuff that's declared in it exported to other programs you just need to preceed
the declaration with "global". So for Inkey() it would be:

-- [Declared in file Inkey.e]
global function Inkey()
    return get_key()
end function

then in some other code after you include the file and you can use Inkey()
freely.

include Inkey.e

integer char
char = 0 

-- Print the pressed key until Q is hit
while char != 'q' do
    char = Inkey()
    ? char
end while
