PFC实例是参照PB6.51版本的PFC的example做的，里面的注释基本都是用中文重新写过，方便大家阅读，本PFC实例没有使用SQLSPY、DEBUG服务和数据窗口属性服务，但是增加了一些实例，如：带进度条的检索工具，SQL语法分析，数据窗口缓存服务等。-PFC PB6.51 example is the reference version of the example of PFC done inside of the Notes which are re-written in Chinese, facilitate reading, the examples do not use PFC SQLSPY, DEBUG window service attributes and data services, but an increase of some examples, such as : the progress of the band Search tools, SQL syntax analysis, data window cache services.

双向循环链表节点：数据域+指针域指针域：一个指针指向前一个同类型节点，另一个指针指向后一个同类型节点（1）设计节点struct db_node{int data;struct db_node * prev;struct db_node * next;};（2）创建空链表//创建了一个只有头节点的双向循环链表，返回头节点的地址struct db_node * create_db_list(void){struct db_node * phead = (struct db_node *)malloc(sizeof(struct db_node));if(phead == NULL)exit(-1);else{phead->next = phead;phead->prev = phead;}return phead;}（3）制造新节点//制造新节点，返回新节点的地址struct db_node * make_db_node(int value){struct db_node * pnew = (struct db_node *)malloc(sizeof(struct db_node));if(pnew == NULL)printf("malloc failed! ");else{pnew->data = value;pnew->next = NULL;pnew->prev = NULL;}return pnew;}（4）插入节点//把pnew指向的节点插入到头节点的前面，也就是整个链表的末尾bo
