Check in /usr/include/tinfo.h.  Include <curses.h> and make sure
M_TERMINFO is defined.

The acsc entry is one of the low level terminfo entries necessary
to draw graphics characters.  Others are sgr, sgr0, smacs and rmacs.

The ACS macros _are_ the standard and recommended way of accessing
alternate character sets for System 5.3 based curses(3).  E.g.

#include <curses.h>

int main()

{
	initscr();
	mvwaddch(stdscr, 0, 0, ACS_ULCORNER);
	mvwaddch(stdscr, 12, 40, ACS_PLUS);
	wrefresh(stdscr);
	endwin();
	return 0;
}

SCO Unix ships with color support in curses as well.  Send e-mail if you
want source to a demo yahtzee game using color window attributes.
