在cobol程序上打开VB文件以处理XML文件时出错
在cobol程序上打开VB文件以处理XML文件时出错
提问于 2021-10-27 09:35:43
长话短说，我需要在cobol程序中处理XML文件，我已经了解到可以使用企业cobol 6.3中的XML解析实用程序来执行此操作。
我没有太多处理可变长度文件的经验，但我们最好的猜测是输入文件可能是可变长度的。我有一个要测试的示例文件，其中包含以下信息屏幕
Data Set Name . . . . : TDES.XML.SPOT.TR

问题是你想处理一个LINE SEQUENTIAL文件，但是指定了一个不同长度的ORGANIZATION SEQUENTIAL，所以你得到了一个你实际上不想要的VB文件(长度填充了4个字节)。
更改为LINE SEQUENTIAL，您可能就很好了。
更多细节可以在IBM Programmer's Guide "Processing line-sequential files"中看到。
