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。它应该读取我文件中的所有记录，然后显示评级为3.5或更高的公司及其信息，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，然后公司中的平均值。我是Cobol的新手，所以我不确定如何找到最高，最低和平均值。我编写了我在模块2012中可以使用的代码来找到最高的但是当我运行我的程序时它不会显示信息。任何有关这方面的帮助将不胜感激。谢谢

我厌恶这种语法。每天给我一袋完整的停止。
8000-READ-MOVING-QUOTES-FILE.
READ MOVING-QUOTES-FILE
AT END MOVE 'T' TO WS-EOF.
MOVE FS-MOVING-QUOTES-RECORD TO

答案 1 :(得分：2)
@Magoo是完全正确的，你还没有结束读取以下几行 是仅在文件结尾处执行
MOVE FS-MOVING-QUOTES-RECORD TO
WS-MOVING-QUOTES-RECORD.
另一种选择是结束阅读
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
.
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，当您对程序进行编号时，应将它们按数字顺序放置
2000年的更多问题 - 执行8000-应该在程序结束时
目前：
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
同样在2012年 - 你为什么要写作，当然这应该在最后完成（第3000节 - ）。
