COBOL输出不变。无法使用记事本查看输出。

我正在尝试查看我正在处理的程序的输出。我被指示使用记事本，但每次打开文件时，我都会得到更改之前的旧输出。我不知道这是编程错误还是我的技术失误。你们能看看有什么事吗

在此处输入代码

通常的嫌疑犯是

你没有改变你认为你在程序中改变的东西

在再次运行程序之前，您没有重新编译该程序，因此您最终运行的是旧版本的程序，当然，它会产生相同的结果

您从另一个文件夹运行该程序，该文件夹将新的输出文件放在您认为的其他文件夹中，因此您不会真正查看新的输出文件

---

再次运行程序时，请确保没有打开输出文件。此外，还可以找到更好的文本编辑器，如记事本+。

删除或重命名“旧”文件以确保安全。 您可以添加“eyecatcher”写入以进行验证。
如果文件时间戳正在更改，但输出不正确，则运行的是旧版本。 您是否已更改代码中的文件名，但正在检查旧名称
