+                structure  (declared  in <STRONG>term.h</STRONG>), and the <EM>dynamic</EM> <EM>variables</EM> on

+                <EM>static</EM>  variables.  They are the same.  Like SVr4 curses, XPG4
+                curses does not initialize these explicitly.

+                variables in persistent storage, initialized to zeros.

+                variables  in  the  same  manner  as   SVr4.    Unlike   other
+                implementations,  ncurses  zeros  dynamic variables before the
+                first <STRONG>%g</STRONG> or <STRONG>%P</STRONG> operator.
