Main data structures and flow control statements are presented.

介绍了主要的数据结构和流程控制语句。

Statement, the free variable is treated as a global.

如果某自由变量的最近封闭作用域包括一个global语句，那么这个自由变量就当作全局变量处理。

If the nearest enclosing scope for a free variable contains a global statement, the free variable is treated as a global.

如果某自由变量的最近封闭作用域包括一个global语句，那么这个自由变量就当作全局变量处理。

The goto statement transfers program execution to some label within the program.

goto语句可跳转到程序内的任一个标签。

Actually, C still has a GOTO statement, but its functionality is limited and it is only recommended a s a last resort if structured solutions are much more complicated.

事实上， C仍然具有GOTO语句，不过它的功能被限制了，仅当结构化方案非常复杂时才建议使用。

Second,I don't think it is wise wo use goto.

其次，我不认为使用"goto"语句是明智的。

The watermark structure was divided into sub-blocks and calculated by linear hashing function, which includes both the sequence information and the quantity information of the nodes. A constant migration technique wraps the integrity checking in the normal logical judgment operation of the watermarked program.

利用线性哈希函数对水印结构进行分块计算，既包含了结点顺序信息，又包含了结点数量信息，同时采用常量迁移技术使完整性检查隐藏在程序本身正常的逻辑判断语句中。
