Cobol错误代码：243是什么意思？

如何解决Cobol错误代码：243是什么意思？

| 在Micro Focus Cobol Eclipse中运行Cobol程序时出现错误。不知道为什么会这样。请帮助我，因为我必须将此作为我明天大作业的一部分提交。另一个问题，如果可能的话，请为我提供变量的帮助，我将其放在“本地存储”部分中。例如，在Java中，我想将其设置为全局方法以获取每种方法？控制文件：

   Identification Division.
    Program-Id. Client.
    Environment Division.
    Configuration Section.
    Repository.
    Class Student.

    Data Division.
    Working-Storage Section.
    01 H object reference Student.

    Procedure Division.

        display \"goodbye goodbye\".                
        Invoke Student \"new\" returning H.
        Invoke H \"sayHello\".
        Invoke H \"GetAverage\" .
        Invoke H \"Grading\".

    Exit Program.
    End Program Client.

这是类文件：

   class-id. Student data is protected 
  *            inherits from base with data
   inherits Base.

   object section.
   class-control.
       Student is class \"student\"
       base is class \"base\"
       .
   working-storage section.


   class-object.
   object-storage section.

   Method-Id. sayHello.
    Procedure Division.
            display \"Hello World!\".
  *         display \"I\'m hello\".
    End Method sayHello.


  *Method1
   method-id. \"GetAverage\".
   local-storage section.

   linkage section.
   01 English  pic 99 value 9.
   01 Math     pic 99 value 5.
   01 AverMark pic 99 value 3.
   procedure division using by reference English,by reference Math.
  *                            returning AverMark.

       COmpuTE AverMark = (English+Math)/2
       display \"Average mark is \",AverMark.
       Accept English.
   exit method.
   end method \"GetAverage\".

  *Method2
   method-id. \"Grading\"
   local-storage section.

   linkage section.
   01 AverMark pic 9.
   01 Grade pic X.
   procedure division using by reference AverMark.
  *                            returning Grade.

   IF AverMark < 5 
       MOVE \"FAIL\" TO Grade
   ELSE 
       MOVE \"PASS\" TO Grade.

   exit method.
   end method \"Grading\".

   end class-object.

   end class Student.

结果是：再见再见执行错误：文件\'Client \' 错误代码：243，pc = 0，调用= 1，seg = 0 找不到243错误讯息文字

解决方法

根据Micro Focus网站上的文档，错误243解释如下。 \“ COBRT243类无法加载（致命）加载对象类的尝试失败，因为该类不包含有效的Class-Control节，或者因为该类的定义不正确。\“ 检查您是否正确定义了Student。
