Sub过程与Function过程最根本的区别是（）。

A．Sub过程的过程不能返回值，而Function过程能返回值

B．Function过程可以有形参，Sub过程不可以

C．Sub过程可以使用Call语句直接使用过程名调用，而Function过程不可以

D．两种过程参数的传递方式不同

答案

参考答案：A

解析：在Visual Basic”中有两类过程，一类是系统提供的内部函数和事件过程；另一类是用户根据自已的需要定义的，供事件过程的多次调用。在第二类过程中，涉及最多的是子过程它们的共同点都是完成某种特定功能的一组程序代码；不同的是函数是可以直接返回值的特殊过程，所以函数过程定义时有返回值的类型说明。两者最大区别就是Sub过程的过程不能直接返回值，而Function过程能直接返回值。
