问题描述
我正在创建一个程序，该程序正在读取包含公司及其信息的文件.它应该读取我文件中的所有记录，然后显示信息评级为3.5或更高的公司，然后拒绝评级低于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水平.我是Cobol的新手，所以我不确定如何找到最高，最低和平均水平.我已经编写了代码，尽管可以在Module 2012中找到最高的代码，但是当我运行程序时它不会显示信息.任何帮助，将不胜感激.谢谢
I am creating a program that is reading in a file which consists of companies and their information. It is supposed to read all the records in my file then display the companies with a 3.5 rating or higher with their information, then it is to reject companies with a rating lower that 3.5 and then display the highest quote and the lowest quote and then the average among the companies. I am new to Cobol so I am not sure how to find the highest, lowest and the average. I have coded what I though would work in Module 2012 to find the highest but when I run my program it does not display the information. Any help with this would be greatly appreciated. Thank you

推荐答案
@Magoo是非常正确的，您尚未结束阅读，因此以下几行 只能在文件末尾执行
@Magoo is quite correct, you have not ended the Read so the following lines are only executed at the end-of-file
MOVE FS-MOVING-QUOTES-RECORD TO
WS-MOVING-QUOTES-RECORD.
另一个选择是结束阅读
8000-READ-MOVING-QUOTES-FILE.
READ MOVING-QUOTES-FILE
AT END MOVE 'T' TO WS-EOF
end-Read
MOVE FS-MOVING-QUOTES-RECORD TO
WS-MOVING-QUOTES-RECORD
.
我个人将移动FS移动"移至2000-或8010-
personally I would move the "Move FS-MOVING" to 2000- or 8010-
2000-READ-N-PRINT-MQ.
MOVE FS-MOVING-QUOTES-RECORD TO
WS-MOVING-QUOTES-RECORD
PERFORM 8010-CHECK-LINES
....
8000-READ-MOVING-QUOTES-FILE.
READ MOVING-QUOTES-FILE
AT END MOVE 'T' TO WS-EOF
end-Read
.
最后一点，当您为过程编号时，应该将它们按数字顺序排列
One final point, when you number procedures they should put them in numeric sequence
2000年的更多问题-性能8000-应该在手术结束时结束
Some more issues in 2000- the perform 8000- should be at the end of the procedure
当前:
2000-READ-N-PRINT-MQ.
* PERFORM 8010-CHECK-LINES
PERFORM 8000-READ-MOVING-QUOTES-FILE
IF (MQR-RATING >= 3.5)
MOVE WS-MOVING-QUOTES-RECORD TO
PRT-MOVING-QUOTES-FILE
PERFORM 2001-PRINT-COMP
PERFORM 2010-FIND-HI-LO-AVG
END-IF
应该是:
2000-READ-N-PRINT-MQ.
* PERFORM 8010-CHECK-LINES
IF (MQR-RATING >= 3.5)
MOVE WS-MOVING-QUOTES-RECORD TO
PRT-MOVING-QUOTES-FILE
PERFORM 2001-PRINT-COMP
PERFORM 2010-FIND-HI-LO-AVG
END-IF
PERFORM 8000-READ-MOVING-QUOTES-FILE
也是在2012年-您为什么要写书，一定要在最后完成(第3000-节).
also in 2012- why are you doing a write, surely this should be done at the end (section 3000-).
