69 the window; all lines below the current line are moved up one line.

75 are lost. For negative <I>n</I>, delete <I>n</I> lines (starting with the one under
76 the cursor), and move the remaining lines up. The bottom <I>n</I> lines are
77 cleared. The current cursor position remains the same.
79 The <B>insertln</B> and <B>winsertln</B> routines insert a blank line above the
