SAS proc compare - 如何将格式应用于输出值

Question

我有2个datetime20的数据集。分配给AEEDTM变量的格式 然而，我只在proc比较输出中显示了datepart：

    var url = NSURL(string: "tel://*105")

    if UIApplication.shared.canOpenURL(url! as URL)
    {
        UIApplication.shared.openURL(url! as URL)
    }
    else
    {
        let alert = UIAlertController(title: "Error", message: "You can't to call.", preferredStyle: .alert)
        alert.addAction(UIAlertAction(title: "Ok", style: .cancel, handler: nil))
        self.present(alert, animated: true, completion: nil)
    }

如何强制SAS在proc compare中打印格式化值？
