我担心的是在过渡期没有一个合法的地址。

My concern is to not have a legal address while in transition.

对内存的操作被允许，但是必须支持地址偏移值，即，对于给出的地址，加上一个偏移量，此时也是一个合法的地址。

"o" : A memory operand is allowed, but only if the address is offsettable. ie, adding a small offset to the address gives a valid address.

集合3：存储那些已知是合法地址的消息。

Set 3: Store messages to known legitimate addresses.

But when you start writing programs, especially when we get to web-based stuff where you want -- to check the user's input -- is it valid, is it an email address, -- and all these different scenarios -- it's actually often useful to be able to just enumerate them or rattle them off using this switching construct instead.

但是当你看是写程序时，特别是当我们,使用基于网络的东西，你想要,检查用户的输入-,它是合法的吗？它是不是一个电子邮箱地址？,所有的这些场景-,实际上它常常是有用的，当你用枚举结构列举它们,或者用它来快速地来说出它们。
