-       <STRONG>initscr</STRONG> is normally the first <STRONG>curses</STRONG> routine to call when  initializing
-       a  program.   A few special routines sometimes need to be called before
-       it; these are <STRONG><A HREF="curs_slk.3x.html">slk_init(3x)</A></STRONG>, <STRONG>filter</STRONG>, <STRONG>ripoffline</STRONG>, <STRONG>use_env</STRONG>.  For multiple-
-       terminal applications, <STRONG>newterm</STRONG> may be called before <STRONG>initscr</STRONG>.
-
-       The  initscr  code  determines  the  terminal  type and initializes all
-       <STRONG>curses</STRONG>  data  structures.   <STRONG>initscr</STRONG>  also  causes  the  first  call  to
-       <STRONG><A HREF="curs_refresh.3x.html">refresh(3x)</A></STRONG>  to  clear  the screen.  If errors occur, <STRONG>initscr</STRONG> writes an
-       appropriate error message to standard error  and  exits;  otherwise,  a

+       <EM>curses</EM> function call a program performs.  However, an application  with
+       unusual needs might employ a few other <EM>curses</EM> functions beforehand:
+
+       <STRONG>o</STRONG>   <STRONG><A HREF="curs_slk.3x.html">slk_init(3x)</A></STRONG> to set up soft-label keys;
+
+       <STRONG>o</STRONG>   <STRONG><A HREF="curs_util.3x.html">filter(3x)</A></STRONG>  if  the  program  is  designed  to operate in a process
+           pipeline;
+
+       <STRONG>o</STRONG>   <STRONG><A HREF="curs_kernel.3x.html">ripoffline(3x)</A></STRONG> to reserve up to five lines at the top and/or bottom
+           of  the  screen  from  management  by  <STRONG>stdscr</STRONG>,  the standard <EM>curses</EM>

+           environment  and  operating system's terminal driver, respectively,
+           when determining the dimensions of the terminal display.
+
+       Further, a <EM>curses</EM> program might call <STRONG>newterm</STRONG> prior  to  or  instead  of
+       <STRONG>initscr</STRONG> in two specialized cases described in its subsection below.
+
+       <STRONG>initscr</STRONG>  causes  the  first  <STRONG><A HREF="curs_refresh.3x.html">refresh(3x)</A></STRONG>  call to clear the screen.  If
+       errors occur, <STRONG>initscr</STRONG> writes an appropriate diagnostic message  to  the
+       standard  error  stream  and  exits; otherwise, it returns a pointer to
+       <STRONG>stdscr</STRONG>.

-       if the terminal cannot support a screen-oriented  program,  would  also

-       which returns a pointer to  a  <EM>TERMINAL</EM>  structure.   <STRONG>newterm</STRONG>'s  return

+           later use with <STRONG>set_term</STRONG> and <STRONG>delscreen</STRONG>.
+

+       at most one terminal connection is needed, the programmer could perform
+       such a capability test, decide which mode in  which  to  operate,  then
+       call  <STRONG>delscreen</STRONG>  on  the  pointer returned by <STRONG>newterm</STRONG>, and proceed with

 .SS initscr
-\fBinitscr\fP is normally the first \fBcurses\fP routine to call when
-initializing a program.
-A few special routines sometimes need to be called before it;
-these are \fBslk_init\fP(3X), \fBfilter\fP, \fBripoffline\fP,
-\fBuse_env\fP.
-For multiple-terminal applications,
-\fBnewterm\fP may be called before \fBinitscr\fP.
-.PP
-The initscr code determines the terminal type and initializes all \fBcurses\fP
-data structures.
-\fBinitscr\fP also causes the first call to \fB\%refresh\fP(3X)
-to clear the screen.
-If errors occur, \fBinitscr\fP writes an appropriate error
-message to standard error and exits;
-otherwise, a pointer is returned to \fBstdscr\fP.
+.B \%initscr
+determines the terminal type and initializes the library's
+.IR SCREEN ","
+.IR WINDOW ","
+and other data structures.
+It is normally the first
+.I curses
+function call a program performs.
+However,
+an application with unusual needs might employ a few other
+.I curses
+functions beforehand:
+.bP
+\fB\%slk_init\fP(3X) to set up soft-label keys;
+.bP
+\fB\%filter\fP(3X) if the program is designed to operate in a process
+pipeline;
+.bP
+\fB\%ripoffline\fP(3X) to reserve up to five lines at the top and/or
+bottom of the screen from management by
+.BR \%stdscr ","
+the standard
+.I curses
+window;
+and
+.bP
+\fB\%use_env\fP(3X) and/or \fB\%use_tioctl\fP(3X) to configure use of
+the process environment and operating system's terminal driver,
+respectively,
+when determining the dimensions of the terminal display.
+.PP
+Further,
+a
+.I curses
+program might call
+.B \%newterm
+prior to or instead of
+.B \%initscr
+in two specialized cases described in its subsection below.
+.PP
+.B \%initscr
+causes the first \fB\%refresh\fP(3X) call to clear the screen.
+If errors occur,
+.B \%initscr
+writes an appropriate diagnostic message to the standard error stream
+and exits;
+otherwise,
+it returns a pointer to
+.BR stdscr "."
 .SS newterm
-A program that outputs to more than one terminal should use the \fBnewterm\fP
-routine for each terminal instead of \fBinitscr\fP.
-A program that needs to inspect capabilities,
-so it can continue to run in a line-oriented mode if the
-terminal cannot support a screen-oriented program, would also use
-\fBnewterm\fP.
-.PP
-The routine \fBnewterm\fP should be called once for each terminal.
-It returns a variable of type \fISCREEN *\fP which should be saved
-as a reference to that terminal.
-\fBnewterm\fP's arguments are
-.bP
-the \fItype\fP of the terminal to be used in place of \fB$TERM\fP,
-.bP
-an output stream connected to the terminal, and
-.bP
-an input stream connected to the terminal
-.PP
-If the \fItype\fP parameter is \fBNULL\fP, \fB$TERM\fP will be used.
-.PP
-The file descriptor of the output stream is passed to \fBsetupterm\fP(3X),
-which returns a pointer to a \fI\%TERMINAL\fP structure.
-\fBnewterm\fP's return value holds a pointer to the \fI\%TERMINAL\fP structure.
+An application that manages multiple terminals should call
+.B \%newterm

+.PP
+.B \%newterm
+passes the file descriptor of the output stream to the

+function \fB\%setupterm\fP(3X),
+which returns a pointer to a
+.I \%TERMINAL
+structure that
+.B \%newterm
+stores in the
+.I SCREEN
+it returns to the application.
+.PP
+An application that needs to inspect a terminal type's capabilities,
+so that it can continue to run in a line-oriented mode
+if the terminal cannot support a screen-oriented program,
+would also use
+.BR \%newterm "."
+If at most one terminal connection is needed,
