Discussion: Roll up.

The (RU) control code moves the entire screen display up one line, rolling the top line completely off the screen. Inserts a blank foreground line at the bottom of the screen. Moves the cursor to the beginning of the inserted blank line (i.e., the lower left corner of the screen).

See Roll Down (RD).
