我在课堂上的任务中遇到了关于我的程序分工的错误。这是一个COBOL计划，应该保持申请人的平均身高和体重，棕色眼睛的申请人数，男性申请人数和女性申请人数的总计。此程序还应打印满足特定要求的申请人的信息，但我几乎所有的执行陈述都会出错
COBCH0034操作数操作数应为数字 在此上下文中需要一个数值，并且您已指定了非数字值。
COBCH0014操作数无效 您指定的操作数在某种程度上是不正确的，并且您的COBOL系统无法处理。例如，您可能指定了一个负整数，其中只允许正整数

答案 0 :(得分：1)
所以你有几件事情在这里出错了。让我详细介绍其中的一些，并给你一些解决方法。
你正在使用句点来结束语句，当你将它与一些较新的语句（以及更新的，我的意思只有30岁）的语句混合时，这很糟糕和糟糕，比如内联执行和读/结束/不是在结束/结束阅读。
而不是：
PERFORM UNTIL EOF = 'Y'
READ INPUT-FILE
AT END MOVE 'Y' TO EOF
NOT AT END
PERFORM 200-HEADING.
PERFORM 200-AVG-HEIGHT.
PERFORM 200-AVG-WEIGHT.
PERFORM 200-BROWN-EYED-APPS.
PERFORM 200-MALE-APPS.
PERFORM 200-FEMALE-APPS.
PERFORM 200-MALE-DETAIL-LINE.
PERFORM 200-FEMALE-DETAIL-LINE.
CLOSE INPUT-FILE, OUTPUT-FILE.
STOP RUN.
你需要这样的东西：
PERFORM UNTIL EOF = 'Y' <--- This is better as an 88 level
READ INPUT-FILE
AT END MOVE 'Y' TO EOF
NOT AT END
PERFORM SOMETHING <--- You need to accumulate you data here
END-READ
END-PERFORM
PERFORM 200-HEADING
PERFORM 200-AVG-HEIGHT
PERFORM 200-AVG-WEIGHT
PERFORM 200-BROWN-EYED-APPS
PERFORM 200-MALE-APPS
PERFORM 200-FEMALE-APPS
PERFORM 200-MALE-DETAIL-LINE
PERFORM 200-FEMALE-DETAIL-LINE
CLOSE INPUT-FILE, OUTPUT-FILE
STOP RUN. <--- This is the only period you need
<--- In your mainline
你不能这样做：
200-AVG-HEIGHT.
IF NOT AT END <--- NOT AT END and AT END only work
<--- in the context of a READ statement
ADD APPLICANTS-HEIGHT TO AVERAGE-HEIGHT
ELSE AT END
DIVIDE AVERAGE-HEIGHT BY 21.
WRITE OUTPUT-REC FROM SUMMARY-LINE-01.
在循环浏览文件时，通过将每个申请人添加到APPLICANTS-HEIGHT并将1添加到您的APPLICANTS-COUNT来累积总高度。当您准备好对高度进行汇总时，请执行以下操作：
200-AVG-HEIGHT.
DIVIDE APPLICANTS-HEIGHT BY APPLICANTS-COUNT
WRITE OUTPUT-REC FROM SUMMARY-LINE-01
. <---- Again, you only need a single period to end a paragraph
在所有段落中，您都在尝试累积数据并编写摘要行。这不起作用。请参阅上面的执行循环，其中包含“执行某些内容以累积您的数据”，这是您希望将所有代码添加到每个申请人的段落。您需要单独的段落来编写摘要行。
所以这应该发生在每一条记录上：
200-MALE-DETAIL-LINE.
IF APPLICANTS-HAIR-CODE = 1
IF APPLICANTS-EYE-CODE = 1
IF APPLICANTS-GENDER = M
IF APPLICANTS-HEIGHT >= 72
IF 185 <= APPLICANTS-WEIGHT <= 200
ELSE CONTINUE. <--- you are doing nothing here
WRITE OUTPUT-REC FROM 01 DETAIL-LINE.
最好这样写：
200-MALE-DETAIL-LINE.
IF APPLICANTS-HAIR-CODE = 1
AND APPLICANTS-EYE-CODE = 1
AND APPLICANTS-GENDER = M
AND APPLICANTS-HEIGHT >= 72
AND (185 <= APPLICANTS-WEIGHT <= 200)
WRITE OUTPUT-REC FROM 01-DETAIL-LINE
END-IF
这应该让你去。您需要将这些提示应用于所有其他段落。简而言之，您的程序通常应如下所示：
Open Files
Perform until EOF
Read a-record
not at end
Perform Do-Detail-Lines
at end
Set EOF to true
End-Read
End-Perform
Perform Do-Summary-Lines
Close files
Stop Run.
Do-Detail-Lines.
...add up all the things you are averaging and counting...
...populate detail line...
write output-rec from detail-line
.
Do-Summary-Lines.
...calculate all averages...
...populate summary line...
write output-red from summary-line
...repeat as needed for other summary-lines...
.
