+======Synopsis:======
+[[window]] toplines [<lines>]
+======Description:======
+This operation reserves <lines> nonscrollable lines at the top of a
+window's display for display of the [[window topline|window's toplines]].
+Each window has 9 toplines, so <lines> must be 0 to 9.  You are permitted
+to change any window topline at any time, even if the topline is not visible.
+Toplines are often used for topic bars, or for showing vital stats about
+the window's current channel that should remain static on the display.

+This operation first appeared in EPIC5-0.0.3
