如果远程数据源不能处理主机变量或参数标记符中的NULL，那么任何需要绑定一个可以为空的值的函数都必须在本地计算。

当在函数或其它地方引用一个全局变量时，脚本引擎需要搜索整个全局命名空间。
Also when a global variable is referenced inside a function or another scope, the script engine has to search through the whole scope to find it.
如果更改了元数据和消息(例如服务器端类或变量)的组织方法，您将会为更改使用这些元数据和消息的客户机脚本验证函数感到十分头痛。
If you change the way you organize metadata and messages (such as the server-side classes or variables), you end up changing client script validation functions that use them.
那些匿名函数所需的本地变量据说被“封闭”(closedover)或“提升”(lifted)到该匿名类中。

不管在哪里声明一个变量或函数，extern关键字都允许其他文件在不确定其定义位置的情况下使用该文件。

如果不能确定为何函数没有按预期工作，用printf或类似的工具在控制台上打印几个变量就可以了解幕后发生了什么。

函数返回特定值(或值范围)以指明错误，且设置全局变量errno以指明问题的起因。
The function returns a specific value (or range of values) to indicate an error, and the global variable errno is set to indicate the cause of the problem.
这里我声明另一个变量，这个完全是合法的因为我已经知道，如果我执行一个像swap，或，increment的函数，我完全可以携带输入。
X so here I'm declaring another variable called X, and this is totally legitimate because I already know that if I'm implementing a function like swap or increment, I can absolutely take input.
这个例子定义了一个函数，它将递增当前缓冲区的b： backup _ count变量的值(或初始化为1，如果尚不存在的话)。
This example defines a function that increments the value of the current buffer's b: backup_count variable (or initializes it to 1, if it doesn't yet exist).
基本上，setup函数采用一组包含一列需要安装的东西(除py _ modules外还可能有packages或ext _ modules或其它东西)的已命名的变量。
Basically, setup takes a bunch of named arguments, including a list of things to install (besides py_modules, there might be packages or ext_modules or some other things).
如果您运行设置变量或包含函数的脚本，以及在同一个上下文中执行的后续脚本，那么可以使用前一个脚本的变量和函数。
If you run a script that sets variables or contains functions, subsequent scripts executed within the same context can use the variables and functions of the previous scripts.
请注意，如果函数、方法、触发器或视图中引用了某个全局变量，则不能删除该变量。
Please note that the global variable cannot be dropped if it is referenced in a function, method, trigger or view.
如果带静态(或全局)变量的迭代器类或函数取决于多个数据状态，则出现两个问题。
If an iterator class or a function with static (or global) variables depends on multiple data states, two problems come up.
这迫使管理员或开发人员不得不经常修改脚本以使用其他值；为了避免这个问题，应该使用变量并为脚本或函数提供参数。
To keep administrators or developers from constantly having to modify a script to work a certain way with other values, use variables and supply arguments to the script or function.
闭包是在它自己的环境中执行计算的函数，它有一个或多个绑定变量可以在调用函数时访问。
A closure is a function that is evaluated in its own environment, which has one or more bound variables that can be accessed when the function is called.
字符串变量的长度：substr函数的输入参数，决定了结果字符串的期望长度或length函数的输出。
Length of a string variable: Input argument for the SUBSTR function, which determines the desired length of the resulting string or output of the length function.
如你所见，类的成员变量的类型是通用类型，但是你可以改进产生器，使之知道一个变量应该包含一个数字或一个函数。
As you can see the type of the class variables is generic, but you can improve the generator to understand if a variable should contain a number or a function.
