Yes, it is missing. That's because there is no "international standard user interface device". Ada is an international standard, so it has to be very careful about specifying things that might not be. > I know there are a lot of terminals, and depends a lot upon > hardware.

At the same time, the "normal" user interface these days is graphical (bitmapped), not command-line or character screens. On adapower.com, you will also find severl non-standard libraries to handle graphical displays. -- -- Stephe
