+       This page summarizes variables provided by the <STRONG>curses</STRONG>  li-
+       brary.   A more complete description is given in the <STRONG>curs-</STRONG>
+       <STRONG><A HREF="ncurses.3x.html">es(3x)</A></STRONG> manual page.
+
+       Depending on the configuration, these may be actual  vari-
+       ables,     or    macros    (see    <STRONG><A HREF="curs_threads.3x.html">curs_threads(3x)</A></STRONG>    and
+       <STRONG><A HREF="curs_opaque.3x.html">curs_opaque(3x)</A></STRONG>) which provide read-only access  to  <EM>curs-</EM>
+       <EM>es</EM>'s  state.   In  either  case, applications should treat
+       them as read-only to avoid confusing the library.
+
+
+</PRE>
+<H3><a name="h3-COLOR_PAIRS">COLOR_PAIRS</a></H3><PRE>
+       After initializing curses, this variable contains the num-
+       ber of color pairs which the terminal can support.  Usual-
+       ly the number of color pairs  will  be  the  product  <STRONG>COL-</STRONG>
+       <STRONG>ORS</STRONG>*<STRONG>COLORS</STRONG>, however this is not always true:
+
+       <STRONG>o</STRONG>   a  few  terminals  use HLS colors, which do not follow
+           this rule
+
+       <STRONG>o</STRONG>   terminals supporting a large number of colors are lim-
+           ited  by  the number of color pairs that can be repre-
+           sented in a <EM>signed</EM> <EM>short</EM> value.
+
+
+</PRE>
+<H3><a name="h3-COLORS">COLORS</a></H3><PRE>
+       After initializing curses, this variable contains the num-
+       ber of colors which the terminal can support.
+
+
+</PRE>
+<H3><a name="h3-COLS">COLS</a></H3><PRE>
+       After  initializing  curses,  this  variable  contains the
+       width of the screen, i.e., the number of columns.
+
+
+</PRE>
+<H3><a name="h3-ESCDELAY">ESCDELAY</a></H3><PRE>
+       This variable holds the number of milliseconds to wait af-
+       ter reading an escape character, to distinguish between an
+       individual escape character entered on the  keyboard  from
+       escape  sequences  sent  by cursor- and function-keys (see
+       <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG>.
+
+
+</PRE>
+<H3><a name="h3-LINES">LINES</a></H3><PRE>
+       After initializing  curses,  this  variable  contains  the
+       height of the screen, i.e., the number of lines.
+
+
+</PRE>
+<H3><a name="h3-TABSIZE">TABSIZE</a></H3><PRE>
+       This  variable  holds  the  number  of columns used by the
+       <EM>curses</EM> library when converting a tab character  to  spaces
+       as it adds the tab to a window (see <STRONG><A HREF="curs_addch.3x.html">curs_addch(3x)</A></STRONG>.
+
+
+</PRE>
+<H3><a name="h3-The-Current-Screen">The Current Screen</a></H3><PRE>
+       This implementation of curses uses a special window <STRONG>curscr</STRONG>
+       to record its updates to the terminal screen.
+
+
+</PRE>
+<H3><a name="h3-The-New-Screen">The New Screen</a></H3><PRE>
+       This implementation of curses uses a special window <STRONG>newscr</STRONG>
+       to  hold  updates  to  the terminal screen before applying
+       them to <STRONG>curscr</STRONG>.
+
+
+</PRE>
+<H3><a name="h3-The-Standard-Screen">The Standard Screen</a></H3><PRE>
+       Upon initializing curses, a default window called  <STRONG>stdscr</STRONG>,
+       which  is  the  size  of  the terminal screen, is created.
+       Many curses functions use this window.
+
+
+</PRE>
+<H2><a name="h2-NOTES">NOTES</a></H2><PRE>
+       The   curses   library   is   initialized   using   either
+       <STRONG><A HREF="curs_initscr.3x.html">curs_initscr(3x)</A></STRONG>, or <STRONG><A HREF="curs_initscr.3x.html">curs_initscr(3x)</A></STRONG>.
+
+       If  <STRONG>curses</STRONG>  is  configured to use separate curses/terminfo
+       libraries, most of these variables reside  in  the  curses
+       library.
+
+
+</PRE>
+<H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
+       ESCDELAY  and TABSIZE are extensions, not provided in most
+       other implementations of curses.
