NEL is defined in ISO8859-1 as code point 0x85. In 8859-1 there are control characters in the range of 0x80 to 0x9f as well as 0x00 to 0x1f. Lots of documentation on 8859-1 skip the control characters, so many folks don't realize this.
I assume that NL is short for newline. A newline is the same thing as a linefeed or LF in Unix and Linux. It is just a different name for the same thing. In EBCDIC codepage 1047 there is a newline at codepoint 15 and a linefeed at codepoint 25. This leads to some confusion in various conversion tables. To add to the confusion z/OS Unix uses newline (15) as the end of line. So if you convert linefeed to linefeed when converting from 8859-1 things don't work. Because of this many EBCDIC to 8859-1 conversion tables convert newline to linefeed, and linefeed to NEL. Have I mentioned my intense dislike for EBCDIC before? -----Original Message----- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] Behalf Of Alan Altmark Sent: Wednesday, July 09, 2008 9:25 PM To: LINUX-390@VM.MARIST.EDU Subject: Re: line end characters (was SFTP versus FTP) On Wednesday, 07/09/2008 at 07:33 EDT, Douglas Wooster/Raleigh/[EMAIL PROTECTED] wrote: > Added one more line separator to the list below.

All ASCII control controls will be 0x01-0x1F. In order to ensure fidelity on a round trip (EBCDIC->ASCII->EBCDIC), what you will find is that EBCDIC values that have no ASCII equivalent will be assigned to ASCII codepoints that have no EBCDIC equivalent. For example, 0x85 in Windows is an ellipsis, which doesn't exist in any EBCDIC code page. In UNIX (ISO 8859-1) and its derivatives, it has no meaning. And since NL doesn't exist in ASCII, 0x15 and 0x85 can be safely transposed. If you found an EBCDIC codepage that *did* have an ellipsis, then the translation for that particular codepage to Windows (1252) would have to find some other ASCII code point to contain the NL.
