If greater than batch files
提问by gm95
I wrote a simple batch file to run Frequently Used websites based on a number selection. Here's the code I have. I am trying to set it so if someone inputs a number 6 or greater it will go to :Nbut whenever I type 6 the batch file exits. I have tried if %input% > 6 goto :Nbut it just tells me I am going to Google.
我写了一个简单的批处理文件来运行基于数字选择的常用网站。这是我的代码。我正在尝试设置它，以便如果有人输入数字 6 或更大的数字，它将转到，:N但每当我输入 6 时，批处理文件就会退出。我试过了，if %input% > 6 goto :N但它只是告诉我我要去谷歌。

Actually, you don't even need a greater feature. All you need to do is add
实际上，您甚至不需要更大的功能。您需要做的就是添加
goto homepagename
Then you will be taken there if none of the if commands execute a goto command.
如果没有任何 if 命令执行 goto 命令，那么您将被带到那里。
For example, this will fix your code:
例如，这将修复您的代码：
@echo off
:Start2
cls
goto Start
