Powershell PS批处理问题

[迷失在冬的夏]

第一段
$User = read-host "用户名"
$PS = read-host "密码"
$IP = read-host "IP地址"
$PassWord = ConvertTo-SecureString -String $PS -AsPlainText -Force
$Credential = New-Object -TypeName "System.Management.Automation.PSCredential" -ArgumentList $User, $PassWord
Enter-PSSession $IP -credential $Credential

第二段
$Server = read-host "服务名称"
$enalbe = read-host "allow允许/block拒绝"
netsh advfirewall firewall set rule name = $Server new action = $enalbe


请问各位大神如何运行完第一段之后，再运行第二段，谢谢。

加判断吧？第一完成为true时执行第二步？
