B. 求解，keil编译无法通过，百度搜不到答案

主要是三个问题：

第一、前面两个警告是说函数定义了却没有调用， 可以不用管。

第二、Error L116的错误是说超过2K的程序都被切掉，没有编译它们了。可能原因：1、你的软件没有注册，使用的评估版，最多只能编译2K程序；2、在下图的Code Rom Size处设置限定了2K。

第三、后面的Error都是RAM空间不够，你可以优化你的程序，或者试试设置下图红线区域的Memory Model：

C. 用keil编译时出现的问题

*** WARNING L15: MULTIPLE CALL TO SEGMENT
SEGMENT: ?PR?_WRITE_COM?时钟
CALLER1: ?PR?TIMER0?时钟
CALLER2: ?C_C51STARTUP
这是说你在‘时钟’这个文本文件中多次调用了‘WRITE_COM’这个子程序，而调它的就是‘TIMER0’‘C_C51STARTUP’。
下面的几句同样是这个原因分别调用了WRITE_DATE，WRITE_SFM，WRITE_NYR，也可能是你不正确的调用了它，你注意一下就行了，你没发数据，我也只能说到这里。

这个就是一楼说的你的软件没有被完全破解，最好到网上去找个注册码，用那注册机太麻烦了，我也就不多说了，最后一句就是目标没有被创建！
