The Scope of a Variable的意思|示意

Because tally is a local variable within the function, it is created anew with each call and falls out of scope and is destroyed automatically when each call returns.

由于tally是函数内的本地变量，它将在每次调用时重新创建并清空范围，并且在每个调用被返回时自动销毁。

Use this function to clear variables of type VARIANTARG (or VARIANT) before the memory that contains the VARIANTARG is freed (as when a local variable goes out of scope).

使用这个函数去清除VARIANTARG(或VARIANT)类型的变量在内存包含的VARIANTARG被释放(当一个局部变量超出作用域时)。

The scope of a per-user variable is set to be visible in "all tests for this user," which makes it visible to all tests being executed by the same virtual user.

前用户变量的范围被设置为在“All tests for this user”中可见，这使得它对相同虚拟用户所执行的所有测试可见。

puts a In Ruby 1.8, this code prints "42", because the block variable a is actually the same a of the containing scope.

puts a 在Ruby 1.8中，这段代码会打印出“42”, 因为块变量a和所包含域中的a就是一个变量。

You can give it a name (that is, a class name), specify parameters (as in a constructor), and even use the .this keyword, which basically means referencing a variable within the scope of the function.

可以给其一个名称（也就是一个类名），指定参数（和在构造函数中一样），甚至可以使用关键字 .this，这意味着在函数范围内引用变量。

Then, a JSP variable named varAlias is created in the page scope of the tag file with jspContext.setAttribute().

然后，通过 jspContext.setAttribute() 在标记文件的页面范围内创建一个名为 varAlias 的 JSP 变量。
