Can't mail you a program from work but if you need to, I can mail you one from home later. However, is is actually very simple.

You just need to include the curses headers. Set up a screen with "initscr()". You probably want to follow that up with "cbreak()" and "noecho()" and you're away. By default, the window you write to is stdscr and you can start playing with all the nice little (n)curses functions. Most of which don't even take an argument so are very simple. When finished, you link your program against "curses" and, on older systems tcap/terminfo as well.

I miss curses programming as there isn't much call for it these days but it was fun. So much fun I once did a "curses.sh" providing most curses functionality for shell scripters but sadly no longer have the code :(

If you want a dumb example :

#include

int main()
{ WINDOW *my_wins[3];
PANEL *my_panels[3];
int lines = 10, cols = 40, y = 2, x = 4, i;

initscr();
cbreak();
noecho();

/* Create windows for the panels */
my_wins[0] = newwin(lines, cols, y, x);
my_wins[1] = newwin(lines, cols, y + 1, x + 5);
my_wins[2] = newwin(lines, cols, y + 2, x + 10);

/*
* Create borders around the windows so that you can see the effect
* of panels
*/
for(i = 0; i < 3; +++i)
box(my_wins[i], 0, 0);

/* Attach a panel to each window */ /* Order is bottom up */
my_panels[0] = new_panel(my_wins[0]); /* Push 0, order: stdscr-0 */
my_panels[1] = new_panel(my_wins[1]); /* Push 1, order: stdscr-0-1 */
my_panels[2] = new_panel(my_wins[2]); /* Push 2, order: stdscr-0-1-2 */

/* Update the stacking order. 2nd panel will be on top */
update_panels();

/* Show it on the screen */
doupdate();

getch();
endwin();
}
