For Next循环使用时，你要执行一段代码多次集数。语法如下：
For counter = initial_value tofinite_value [Step increment]
statements
Next
For语句指定计数器变量及其初步和有限的价值。 Next语句增加了对抗一个变量。可
选的步骤关键字允许增加或减少的值指定计数器变量。
有一个很简单的例子：
<%@ language="vbscript" %>
<%
For i = 0 to 10 Step 2 'use i as a counter
response.write("The number is " & i & "<br />")
Next
%>
复杂实例
Select ActionSelect AllTry It<%@ language="vbscript" %>
<%
response.write("<h1>Multiplication table</h1>")
response.write("<table border=2 width=50%")
For i = 1 to 9'this is the outer loop
response.write("<tr>")
response.write("<td>" & i & "</td>")
For j = 2 to 9'inner loop
response.write("<td>" & i * j & "</td>")
Next 'repeat the code and move on to the next value of j
response.write("</tr>")
Next 'repeat the code and move on to the next value of i
response.write("</table>")
%>
