【简答题】
①首先利用表设计器在考生目录下建立表newcj.dbf，表结构如下： 民族 字符型(4) 语文平均分 数值型(7,2) 数学平均分 数值型(7,2) ②然后在考生文件夹下创建一个下拉式菜单smenu.mnx，并生成菜单程序smenu.mpr。运行该菜单会在当前’Visual FoxPro系统菜单的末尾追加一个“考试测试”菜单。 ③菜单命令“统计”和“返回”的功能都通过执行过程完成。 ④菜单命令“统计”的功能是根据xs表和cj表分别统计汉族学生和少数民族学生在“语文”和“数学”两门课程上的平均分，并把统计数据保存在表newrcj中。表newcj的结果有两条记录：第1条记录是汉族学生的统计数据，“民族”字段填“汉”；第2条记录是少数民族学生的统计数据，“民族”字段填“其他”。 ⑤菜单命令“返回”的功能是恢复标准的系统菜单。 ⑥菜单程序生成后，运行菜单依次执行“统计”和“返回”菜单命令。
