The simplest flow control statement is the if statement, whose basic syntax is demonstrated in the pseudocode shown in Listing 4.

最简单的流控制语句是 if 语句，它的基本语法在清单 4 中的伪代码中演示了。

With tighter control over the precise syntax of the WSDL being provided to the flow, the scenario's complexity could be significantly reduced.

通过更严格地控制向流提供的WSDL的准确语法，可以极大地降低方案的复杂性。

So let's look at a little example, and this is going to, excuse me, both allow us introduce the syntax as well as what we want to have as the flow of control inside of here.

让我们看个小例子，这个程序会，对不对，请允许我,一边顺着控制流进行,一边讲解语法。
