【问题描述】：
我正在创建一个程序，该程序正在读取由公司及其信息组成的文件。就是拒绝评级低于3.5的公司，然后显示最高报价和最低报价，然后显示公司之间的平均值。我是 Cobol 的新手，所以我不知道如何找到最高、最低和平均值。我已经编写了我想在模块 2012 中工作的代码以找到最高值，但是当我运行我的程序时，它不显示信息。对此的任何帮助将不胜感激。谢谢你

哇。全班都会在这里发问题吗？你是最近几天的第三个。为你的同事失败的 END-READ 喝彩。 所有 IF 都需要END-IF。您不需要在代码中附加任何句号/句点，只需要段落末尾的那些孤独的句号。
-
比尔这个问题包括第一个问题的结束阅读建议
-
@BruceMartin 你的意思是
end-READ是赠品？ :-) -
查看
2011-STORING-VAL-HI，然后查看PERFORM该段的位置，然后立即查看IF。您的想法基本上是正确的，但是在处理记录时只存储值，当时不要尝试将它们写出来，因为直到最后您才知道最高和最低（请记住它们可能是相同的记录）。 -
通读 cmets 和其他两个问题的答案。请注意@BruceMartin 关于段落前缀数字的观点。此外，您的 hi/low/avg 的相同段落将按记录处理，并在最后处理。那是行不通的。你也有我认为的语法错误。你用的是哪个编译器？
