 .SH DESCRIPTION
 The \fBdeleteln\fR and \fBwdeleteln\fR routines delete the line under the
 cursor in the window; all lines below the current line are moved up one line.
-The bottom line of the window is cleared.  The cursor position does not change.

+.PP
 The \fBinsdelln\fR and \fBwinsdelln\fR routines, for positive \fIn\fR, insert
-\fIn\fR lines into the specified window above the current line.  The \fIn\fR
-bottom lines are lost.  For negative \fIn\fR, delete \fIn\fR lines (starting
-with the one under the cursor), and move the remaining lines up.  The bottom
-\fIn\fR lines are cleared.  The current cursor position remains the same.

 .SH RETURN VALUE
 All routines return the integer \fBERR\fR upon failure and an \fBOK\fR (SVr4
 specifies only "an integer value other than \fBERR\fR") upon successful
 completion.
+.PP
+X/Open defines no error conditions.
