COBOL文件转储...

本文介绍了COBOL文件转储...的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

唉，我投降...... 在来自COBOL转储的文件中，该文件是ASCII格式，其中一个字段定义为 as S9（9）V99值+0。 此位置的值为0000018922D，根据 的作者来源，转换为00000189224. 如何通过.Net翻译？我已经尝试过StreamReader并尝试将转换为字节，但我最终得到了相同的值（0000018922D）。 在此先感谢。 Morgan

Alas, I surrender... In a file from a COBOL dump, which is in ASCII, one of the fields is defined as S9(9) V99 Value +0. The value in this location is 0000018922D, which according to the author of the source, translates to 00000189224. How can this be translated via .Net? I''ve tried StreamReader and trying to convert everything to bytes, but I end up with the same value (0000018922D). Thanks In Advance. Morgan

推荐答案

这是所谓的压缩十进制的表示。在最后一个半字节中带有 符号（+或 - ）的字段。在Cobol中称为COMP-3字段。在一个 压缩十进制字段中，每个十进制数字存储在一个半字节中（4位，半个/ b $ b字节）。如果为正，则符号为C或F，如果为负则为符号。 因此在您的示例中，de字段中的值为-189.22。 这是一个相当不错的URL解释： digilander.libero.it/foxes/ Packed_Decimal.htm 希望这会有所帮助， / Ger " MPF" < AB ** @ senditon> schreef in bericht 新闻：Ol ************** @ TK2MSFTNGP15.phx.gbl ... This is the representation of a so called "packed decimal" field with the sign (+ or -) in the last nibble. In Cobol terms a COMP-3 field. In a packed decimal field each decimal digit is stored in a nibble (4-bits, half byte). The sign is C or F if positive, D if negative. So in your example the value in de field is -189.22. Here is a URL with a fairly good explanation: digilander.libero.it/foxes/Packed_Decimal.htm Hope this helps, /Ger "MPF" <ab**@senditon> schreef in bericht news:Ol**************@TK2MSFTNGP15.phx.gbl... 唉，我投降了。 .. 在来自COBOL转储的文件中，其中一个字段是，定义为S9（9）V99值+0。这个位置是0000018922D，根据作者的来源，翻译为00000189224. 如何通过.Net翻译？我已经尝试过StreamReader并尝试将所有内容转换为字节，但最终得到的值相同（0000018922D）。 在此先感谢。 摩根 Alas, I surrender...

MPF， 这应该很容易翻译，唯一的问题是要知道转换为ASCII时使用的 表示为+0和-0 在这个序列中是A + 1（这是EBCDIC中的穿孔卡代码12 + 1） EBCDIC 最后一个位置被告知整个字段为正或负。 因此，例行程序很安静，但是在你的情况下，+ 0和-0翻译为什么是。 Cor " MPF" < AB ** @ senditon> schreef in bericht 新闻：Ol ************** @ TK2MSFTNGP15.phx.gbl ... MPF, This should be easy to translate, the only problem is to know the representation that is used while converted to ASCII for +0 and -0 In this sequence is A +1 (which is punched card code 12 + 1) in EBCDIC and J is -1 however what is -0. (which is punched card code 11 + 1) in EBCDIC With that last position is told that the whole field is plus or minus. Therefore a routine is quiet easy however what is that +0 and -0 translated to in your situation.
