beginner:
    if(!pc) {
	i = rn2((int)strlen(pl_classes));
	pc = pl_classes[i];
	tty_putstr(BASE_WINDOW, 0, "");
	Sprintf(pbuf, "This game you will be %s.", an(roles[i]));
	tty_putstr(BASE_WINDOW, 0, pbuf);
	tty_putstr(BASE_WINDOW, 0, "");
	tty_display_nhwindow(BASE_WINDOW, TRUE);
	getret();
    }
got_suffix:

    tty_clear_nhwindow(BASE_WINDOW);
    pl_character[0] = pc;
    return;
