Assignment To A Variable的意思|示意

A new assignment makes an existing variable refer to a new value (and stop referring to the old value).

一次新的赋值使得已有的变量获得新的值(也就不再有旧的值了。)

By default, a variable is scoped to the function in which it is first assigned to, or is global if its first assignment occurs outside any function.

默认情况下，变量的范围是变量第一次被分配到的函数的内部，如果它的第一次分配出现在任何函数的外部，那么它就是全局变量。

Subsequently, its value is set to an order number returned by a custom code action by using a variable assignment action.

随后，它的值会设置为一个顺序号，它是由使用变量分配操作的通用代码所返回的。

An array variable holds a pointer to the data constituting the array elements and the rank and length information, and an assignment copies only this pointer.

数组变量持有一个指针，它指向构成数组元素的数据及秩和长度信息，赋值语句仅复制此指针。

In many ways, for is the assignment of a variable to the current value in a node set, so you can operate on that variable.

在很多方面，for就将节点集的当前值赋给变量从而操作该变量。

This in turn means it cannot be used as a definite assignment to a variable.

反过又意味着，分部方法不能作为一个明确分配的变量。
