小弟最近做一实验，要求用汇编编写，由于小弟才疏学浅，只学过C#，对汇编题目一筹莫展，劳烦各位高手帮忙，题目如下：

1 实验题目：查找电话号码phone

2 实验要求：1）要求程序建立一个可存放50项的电话号码表，每项包括人名（20个字符）及电话号码（8个字符）两部分；

         2）程序可接收输入人名及相应的电话号码，并把他们加入到电话号码表中。

         3）凡有新的输入后，程序应按人名对电话号码表进行重新排序。

         4）程序可接收需要查找电话号码的人名，并从电话号码表中查出其电话号 码，再在屏幕上以如下格式显示出来。

     name     tel。  

    dkljfa    111111

5)要求有主菜单，至少应有五个以上的独立的模块。

下面是我编出来的程序，可是有错误，大家帮忙看看好吗？
