Question

我正在尝试查看我正在处理的此程序的输出。我被指示使用记事本，但每次打开文件时，我都会获得旧的输出，然后再对其进行更改。我不知道这是编程错误还是技术问题。你们可以看一看，看看有什么问题吗？

在这里输入代码

Answer 1

通常的嫌疑人是

你没有改变你认为你在程序中改变了什么。
在再次运行程序之前，您没有重新编译该程序，因此您最终运行了该程序的旧版本，当然也产生了相同的结果。
您从另一个文件夹运行程序，该文件夹将新的输出文件放在您认为的其他文件中，这样您就不会真正查看新的输出文件。

Answer 2

确保在再次运行程序时没有打开输出文件。另外，找一个更好的文本编辑器，如Notepad ++来使用。

Answer 3

删除或重命名＆＃34; old＆＃34;文件确定。你可以添加＆＃34; eyecatcher＆＃34;写作验证。
如果文件时间戳正在更改但输出不是您正在运行旧版本。您是否更改了代码中的文件名但正在检查旧名称？

COBOL输出没有变化。用记事本看输出有问题。
