Question

我正在尝试以索引方式打开文件，但不断收到以下错误。从我能找到的所有COBOL代码示例中，我看不出我的错误在哪里。

我可以按顺序打开文件就好了。这似乎是试图将其打开为索引。

错误：

project2.cbl:119: libcob: Permanent file error (STATUS = 30) File : 'customers.dat'

Answer 1

无法将顺序文件作为索引文件打开。这是一种完全不同的文件类型。

您可能需要OPEN OUTPUT CUST-FILE，从顺序文件和WRITE CUST-FILE FROM seq-record读取您的客户。之后您的OPEN INPUT CUST-FILE将起作用（取决于您想要实现的目标，最好将数据读入临时和有序表中，然后使用SEARCH ALL获取特定记录。
