我有以下 Cobol 程序，我正在尝试重构它以使其正常工作。该程序应该读取输入文件并输出一些统计信息。我收到一个重大错误和一个警告。我添加了一堆我自己的代码并且它可以编译。

我收到的错误是：
libcob: error: WRITE not allowed, file not open for output (status = 48) for file output-file ('output_dat' => output.dat).
我相信初始化是正确的，但它仍然没有运行完成。
另外，我收到一条编译警告，它表示以下几行存在移动重叠：
62 READ INPUT-FILE INTO INPUT-VALUE-RECORD
在前体的开始处，并且
87 READ INPUT-FILE INTO INPUT-VALUE-RECORD
在输入循环中。我知道我可以用临时变量解决这个问题，但是还有其他方法吗？ WRITE not allowed 错误的解决方案是什么？
