It depends on what kind of terminal you're using. If you're using a terminal emulator like Accuterm, there are command to set and clear an arbitrary block on the screen. If you're using a vt100-type terminal or emulator, you can set a scrolling region and then clear the region (by scrolling it). On a wyse terminal, you can print the parts of the screen you want to not clear using the protected attribute, and the part that you want to clear using unprotected, and then use the clear unprotected control sequence. Universe has @() entries for turning on and off protected mode and clearing unprotected, but I don't think it has any predefined entries for scrolling regions.
