获取错误不太清楚为什么这是我的第一个cobol程序

我正在慢慢地学习COBOL，并且正在做一些挑战来变得更好，但我有一个奇怪的问题，我似乎无法追踪，我想看看是否有其他人可以帮助我

我反复检查了A区和B区的正确列数

IDENTIFICATION DIVISION.

        MOVE WS-AREA TO WS-DISPLAY-AREA.
        DISPLAY "Circle area is:  ", WS-DISPLAY-AREA

        STOP RUN

将程序放入在线编译器代码+结果后，发现两个问题：

打字错误：WS-CircurFrence->WS-CircurFence 末尾缺少分隔符周期 由于您似乎不使用自由格式，而是基于列的格式，我已从该项目中删除了该选项-自由，修复了上面指定的问题，并添加了最小缩进，结果：

我考虑过可能出现的问题，但我能想到的唯一一个问题是小数点的附加规范是逗号，但这会引起错误：级别编号“14159”无效，或者可能出现错误的缩进；您可能需要重新检查是否不按制表符进行缩进。在编辑器显示的内容和编译器使用的内容之间，它们的实际大小可能不同[大多数编译器默认使用8个空格。

除了上述建议之外，我还将添加更改

COMPUTE WS-RADIUS = WS-PI * WS-RADIUS * WS-RADIUS.

到

或者，您将始终为区域打印0

COMPUTE WS-AREA = WS-PI * WS-RADIUS * WS-RADIUS.
