Loops COBOL-EXIT语句异常行为
我在用COBOL编写代码时遇到了一个奇怪的问题 我对这些执行语句进行了编码：Loops COBOL-EXIT语句异常行为,loops,exit,cobol,Loops,Exit,Cobol,我在用COBOL编写代码时遇到了一个奇怪的问题 我对这些执行语句进行了编码： PERFORM 000-INITIAL THRU 000-INITIAL-EXIT. PERFORM 100-MAIN-PROCESS THRU 100-MAIN-PROCESS-EXIT UNTIL END-OF-FILE. PERFORM 900-END-PGM THRU 900

有人知道为什么会这样吗？有解决办法吗
更新：
更正了文件中读取的句子，复制了错误的代码GO TO 900-END-PGM
只是我使用的临时修复程序，以便程序能够正确运行。
我对这个问题也很确定，因为我已经观察到了如何使用调试工具逐行运行这个程序

这可能是原因，也可能不是原因（我们不能说没有检查代码的可能性），但您的程序会中断程序流，因为：
READ IN-FILE AT END MOVE 'Y' TO SW-EOF
GO TO 900-END-PGM.
100-MAIN-PROCESS-EXIT.
EXIT.
如果到达文件末尾，您可以设置end-OF-file
（至少我可以假设这一点，不需要检查代码，如果您使用将end-OF-file设置为TRUE
而不是将“Y”移动到SW-EOF
btw），然后转到900-end-PGM，这可能会更干净。
。
您永远无法到达段落100-MAIN-PROCESS-EXIT.
，因此您的主循环仍将处于活动状态
900-END-PGM
看起来像什么？代码放在哪里（是否都“在”您的主执行到s
附加说明：EXIT
语句是一个no-op语句，您可以用CONTINUE
替换它，以更清楚地了解它的实际功能。“EXIT”只是一种注释，“我们在某处使用PERFORM-THRU
并在此处结束”.由@SimonSobisch提供，通过将条目
语句移出PERFORM 000-INITIAL
，可以解决此问题，如下所示：
我想看看PERFORM 900-END-PGM
和100-MAIN-PROCESS
之间的代码。如果没有停止运行/goback，程序将从PERFORM 900-END-PGM
到100-MAIN-PROCESS
@BruceMartin我已经用上述代码更新了问题code@AnthonyPangestu-你在debu中验证了吗gger，您没有使用条目进入程序，而是以程序部分开始进入程序？@SimonSobisch既然您提到了它，程序执行的程序部分的第一行是在文件中打开输入
，而不是执行000-INITIAL
@AnthonyPangestu那么您就有了答案，不是吗你说呢？这不是禁止操作。这是有条件的返回。如果代码在执行语句的控制下，它将返回到执行。@EJP我很确定退出段落
和退出部分
语句退出相应的过程，退出程序
，退出函数
，退出方法
，其范围（类似于GOBACK
）但是，<代码>退出>代码>将不起作用。在<<代码>执行< <代码> >代码>代码>退出/代码>中间的任何地方都不会做任何事，是吗？我只能重复。在执行语句的控制下，退出语句退出执行。请在“EJP”中讨论这一点。这是错误的。EXIT语句仅用于允许用户将过程名称分配给过程划分中的给定点。这样的EXIT语句对编译或执行没有其他影响。
通常使用条目
，而不是使用
di将参数添加到过程划分中，这仍然是一个问题直截了当地。。。
