接着呼叫你的计算机代码。

You call up your computer code.

注意，上面那些例子指的是不在 z/OS 操作系统控制下运行的计算机代码。

Notice that the examples above refer to computer code that does not run under control of the z/OS operating system.

当您编写与关系数据库（例如 DB2）交互的计算机代码时，必须考虑两个关键要素。

When you write computer code that interacts with relational databases such as DB2, you have to consider two key items.

So now, in this case, this code is going to, when we get here, check, and if you haven't seen that strange thing there, that exclamation point in bang computer-ese called a bang, it says x if ANS star ANS is not equal to x, all right?

那么现在，在这个例子中，当我们执行到这里，代码会去检查,如果你没有看到过这个奇怪的东西,这个感叹号在计算机学中被叫做,代码的意思是如果ANS的平方不等于？
