73 are lost. For negative <EM>n</EM>, delete <EM>n</EM> lines (starting with the one under
74 the cursor), and move the remaining lines up. The bottom <EM>n</EM> lines are
75 cleared. The current cursor position remains the same.
77 The <STRONG>insertln</STRONG> and <STRONG>winsertln</STRONG> routines insert a blank line above the cur-
78 rent line and the bottom line is lost.
