This + involves moving the lines in the window data structure. + As an optimization, if the scrolling region of the window + is the entire screen, the physical screen may be scrolled + at the same time. + + For positive <I>n</I>, the <B>scrl</B> and <B>wscrl</B> routines scroll the + window up <I>n</I> lines (line <I>i</I>+<I>n</I> becomes <I>i</I>); otherwise scroll + the window down <I>n</I> lines. This involves moving the lines + in the window character image structure.
