使用记录编辑器/Jrecord解压缩COMP-3位数字 [英] Unpacking COMP-3 digit using Record Editor/Jrecord

问题描述

我已经基于cobol字帖创建了版面.

I have created layout based on cobol copybook.

布局快照:

我也尝试选择相同的布局来加载数据，这对某些列给了我错误的结果.我尝试使用所有二进制数字类型.

I tried to load data also selecting same layout, it gives me wrong result for some columns. I try using all binary numeric type.

1. CLASS-ORDER-EDGE
2. DIV-NO-EDG
3. OFFICE-NO-EDG
4. REG-AREA-NO-EDG
5. CITY-NO-EDG
6. COUNTY-NO-EDG
7. BILS-COUNT-EDG
8. REV-AMOUNT-EDG
9. USAGE-QTY-EDG
10. GAS-CCF-EDG

推荐答案

第一个问题是您对文件进行了 EBCDIC-> ascii 转换！!!!

First Problem you have done an EBCDIC --> ascii conversion on the file !!!!

EBCDIC-> ascii 转换还将尝试转换二进制字段和文本.

The EBCDIC --> ascii conversion will also try and convert binary fields as well as text.

例如:

Comp-3 value   hex     hex after Ascii conversion

 400          x'400c'       x'200c'       x'40' is the ebcdic space character
                                          it gets converted to the ascii
                                          space character x'20'

您需要执行二进制传输，将文件保留为ebcdic:

---

You need to do binary transfer, keeping the file as ebcdic:

1. 检查大型机上的文件是否具有RECFM = FB，您可以进行传输
2. 如果文件为RECFM = VB，请确保传输 RDW(记录描述符词)<​​/strong>(或将VB文件复制到大型机上的FB文件).

其他要点:

Other points:

您将必须更新RecordEditor/JRecord

You will have to update RecordEditor/JRecord

• 字体必须为ebcdic(美国ebcdic为cp037；其他查找为文件结构/文件组织需要更改(固定长度/VB)

• The font will need to be ebcdic (cp037 for US ebcdic; for other lookup)
• The FileStructure/FileOrganisation needs to change (Fixed length / VB)

最后

• BILS-Count-EDG的长度为9个字符，或者从第85列开始(长度为8个字节).
• 您应将Xml作为文字包含在内，而不要在其中复制图片.
• 在RecordEditor中，如果您右键单击>>>编辑记录；它将显示字段为值"，原始文本"和十六进制".这对于查看发生了什么情况很有用
• 您似乎并没有接受很多答案；答案是否能解决您的问题并不重要；是答案是否是问题的正确答案.

• BILS-Count-EDG is either 9 characters long or starts in column 85 (and is 8 bytes long).
• You should include Xml in as text not copy a picture in.
• In the RecordEditor if you Right click >>> Edit Record; it will show the fields as Value, Raw Text and Hex. That is useful for seeing what is going on
• You do not seem to accept many answers; it is not relevant whether the answer solves your problem; it is whether the answer is correct answer for the question.
