IGZ0020S A logic error occurred. Neither FILE STATUS nor a declarative was specified for file CUSTRECS in program
TOPACCTS at relative location X'414'. The status code was 46.
From compile unit TOPACCTS at entry point TOPACCTS at compile unit offset +00000414 at entry offset +00000414
at address 1B800414.
如果您使用的是大型机 COBOL 编译器，请转到文档并选择您的版本。然后搜索“文件状态键”并查看文件状态 46 的含义。
尝试对以输入或 IO 模式打开的文件执行顺序 READ 语句，但未建立有效的下一条记录，因为：
- 前面的 READ 语句不成功，但没有导致结束条件。
- 前面的 READ 语句导致了结束条件。
请注意，在您的OPEN-FILES段落中，您PERFORM READ-NEXT-RECORD然后在已经到达文件末尾后进入其余代码。
您可能希望在第一段的末尾使用STOP RUN或GOBACK。
关于打印记录数的编辑：确实没有一个好方法让记录数出现在报告的顶部，因为在您阅读整个输入文件之前您不知道记录数，但您正在打印随时报告行。大多数情况下，像记录计数这样的控制总数是DISPLAYed（默认情况下会转到 SYSOUT DD），并且报告会转到FILE-CONTROL（通过 a 中定义的不同 DD WRITE，就像您正在执行的操作一样）。
关于打印记录计数的第二次编辑：正如@GilbertLeBlanc 指出的那样，您可以将输出行存储在表中，直到读取输入文件中的所有记录。您必须在表中有足够的空间来处理所有输出记录，并且有许多不同的方法可以做到这一点。
OCCURS子句静态定义，以处理您被告知的合理数量的记录。这在过去很常见，并且会有代码来检查是否超出了合理数量，如果超出则异常终止。UNBOUNDED短语一起出现，受其限制以及使用ALLOCATE语句和FREE语句管理的存储的约束。吉尔伯特还指出，您可以读取文件两次，一次是获取记录数，然后关闭并重新打开以进行正常处理。只要您不使用 JCL 做一些棘手的事情，例如......
//TOPACCTS EXEC PGM=TOPACCTS
//SYSOUT DD SYSOUT=*
//CUSTRECS DD DISP=SHR,DSN=MY.INPUT.FILE01
//CUSTRECS DD DISP=SHR,DSN=MY.INPUT.FILE02
//CUSTRECS DD DISP=SHR,DSN=MY.INPUT.FILE03
//PRTLINE DD SYSOUT=*
//PRTLINE DD SYSOUT=*
//PRTLINE DD SYSOUT=*
...每次关闭和打开 CUST-RECS 和 PRINT-LINE 时，您都会得到下一个 DD。但这是一个更高级的 JCL 主题，您在实践中可能不会经常遇到。
