  • There are two mappings of LF and NEL used by EBCDIC systems. The first EBCDIC column shows the MVS Open Edition (including CP1047) mapping of these characters, while the second column shows the CDRA mapping. This difference arises from the use of LF character as 'New Line' in ASCII-based Unix environments and in some data transfer protocols that use the Unix assumptions. The second column is based on the standardized definitions — both in ASCII and EBCDIC of LF.
  • NEL is not actually defined in ASCII: it is defined in ISO 6429 as a C1 control.
