Sub procedure
The sub procedure does not return a value.
sub程序不会返回值

Function procedure
The function procedure is used if you want to return a value.
当你想返回值可以使用函数程序

VBScript Procedures
VBScript程序

We have two kinds of procedures: The Sub procedure and the Function procedure.
我们来看看这两种程序:Sub程序和Function(函数)程序

A Sub procedure:
Sub程序：

• is a series of statements, enclosed by the Sub and End Sub statements
  位于Sub和End Sub之间的一系列声明
• can perform actions, but does not return a value
  可以执行动作，但不能返回值
• can take arguments that are passed to it by a calling procedure
  通过调用程序还能获取带来的参数
• without arguments, must include an empty set of parentheses ()
  如果没有参数，必须含有空括号()

Sub mysub()
 some statements
End Sub

Sub mysub(argument1,argument2)
 some statements End Sub 

A Function procedure:
函数程序：

• is a series of statements, enclosed by the Function and End Function statements
  位于Function和End Function之间的一系列声明
• can perform actions and can return a value
  可以执行行为同时还能返回值
• can take arguments that are passed to it by a calling procedure
  通过调用程序还能获取带来的参数
• without arguments, must include an empty set of parentheses ()
  如果没有参数，必须含有空括号()
• returns a value by assigning a value to its name
  通过给它的名称赋值来返回执行程序后的返回值

Function myfunction()
 some statements
 myfunction=some value
End Function

Function myfunction(argument1,argument2)
 some statements
 myfunction=some value
End Function

Call a Sub or Function Procedure
调用Sub或是Function程序

When you call a Function in your code, you do like this:
当你在代码中要调用Function的时候你可以这样：

name = findname()

Here you call a Function called "findname", the Function returns a value that will be stored in the variable "name".
这个时候你已经调用了一个名为"findname"的Function(函数)了。函数会把产生的值返回到并存储到变量"name"中

Or, you can do like this:
或者，你可以这样做：

msgbox "Your name is " & findname()

Here you also call a Function called "findname", the Function returns a value that will be displayed in the message box.
这样你也是调用了名为"findname"的函数，它会将返回的结果连同前面的字符串一起显示在信息框中。

When you call a Sub procedure you can use the Call statement, like this:
当你要调用Sub程序的时候可以使用Call声明，像这样：

Call MyProc(argument)

Or, you can omit the Call statement, like this:
或者你可以将Call忽略掉这样声明：

MyProc argument
