windows() { window(1,1,80,25); textbackground(2); textcolor(5); clrscr(); gotoxy(24,5); cprintf("please choose:"); gotoxy(24,7); cprintf("[1]insert."); gotoxy(24,9); cprintf("[2]quick."); gotoxy(24,11); cprintf("[3]bubble."); gotoxy(24,13); cprintf("[4]select."); gotoxy(24,15); cprintf("[5]exit."); gotoxy(24,17); cprintf("[ ]"); gotoxy(25,17); }

这是定义文本窗口的程序，编译时能够通过，但运行时却出现了黑屏，我定义了 window(1,1,80,25); textbackground(2); 应该是全屏都是绿色背景，但却出现了上面是绿屏，下面是黑屏的情况，小弟实在不懂。望各位高手赐教！
