reborg used the _ character to delimit the sed command. he could have used / but it would have made it even harder to read. It's best to use a character the shell won't try to interpret. _ is one of those.

CURSES_ADDSTR(3)					   BSD Library Functions Manual 					  CURSES_ADDSTR(3)

NAME
curses_addstr, addstr, waddstr, addnstr, waddnstr, mvaddstr, mvwaddstr, mvaddnstr, mvwaddnstr -- curses add character strings to windows rou- tines LIBRARY
Curses Library (libcurses, -lcurses) SYNOPSIS
#include <curses.h> int addstr(const char *string); int waddstr(WINDOW *win, const char *string); int mvaddstr(int y, int x, const char *string); int mvwaddstr(WINDOW *win, int y, int x, const char *string); int addnstr(const char *string, int len); int waddnstr(WINDOW *win, const char *string, int len); int mvaddnstr(int y, int x, const char *string, int len); int mvwaddnstr(WINDOW *win, int y, int x, const char *string, int len); DESCRIPTION
These functions add character strings to stdscr or to the specified window. The addstr() function will add the characters passed in string to stdscr starting at the current cursor position. Any background attributes currently set on stdscr will be applied to the added character. The waddstr() function does the same as addstr() but adds the string to the window specified by win(). The addnstr() function will add the contents of string to stdscr but will limit the number of characters added to be, at most, len. If len is -1 then addnstr will add the number of characters contained in the null terminated string string. Any background attributes currently set on stdscr will be applied to the added character. The waddnstr() function does the same as addnstr but adds the string to the window speci- fied by win. The functions mvaddstr(), mwaddnstr(), mvwaddstr() and mvwaddnstr() are the same as the functions addstr(), waddstr(), waddstr() and waddnstr(), respectively, excepting that wmove() is called to move the cursor to the position specified by y, x before the string is added to the window. RETURN VALUES
Functions returning pointers will return NULL if an error is detected. The functions that return an int will return one of the following values: OK The function completed successfully. ERR An error occurred in the function. SEE ALSO
curses_addch(3), curses_addchstr(3), curses_attributes(3), curses_cursor(3), curses_inch(3) STANDARDS
The NetBSD Curses library complies with the X/Open Curses specification, part of the Single Unix Specification. HISTORY
The Curses package appeared in 4.0BSD. BSD
