![]() RMS not only stored records, but also stored metadata about the record separators in different bits for the file to complicate matters even more (since files could have fixed length records, records that were prefixed by a count or records that were terminated by a specific character). The records themselves could contain the same line terminator characters, which could either be considered a feature or a nuisance depending on the application. In most file formats, no line terminators are actually stored, but the Record Management Services facility can transparently add a terminator to each line when it is retrieved by an application. ![]() RSX-11 and OpenVMS also use a record-based file system, which stores text files as one record per line.Some configurations also defined a zero-valued character as a colon character, with the result that multiple colons could be interpreted as a newline depending on position. Operating systems for the CDC 6000 series defined a newline as two or more zero-valued six-bit characters at the end of a 60-bit word.In most file formats, no line terminators are actually stored. However, those operating systems use a record-based file system, which stores text files as one record per line. Additionally, some EBCDIC variants also use NL but assign a different numeric code to the character. EBCDIC also has control characters called CR and LF, but the numerical value of LF ( 0x25) differs from the one used by ASCII ( 0x0A). ![]() The equivalent Unicode character ( 0x85) is called NEL (Next Line). ![]() EBCDIC systems-mainly IBM mainframe systems, including z/OS (OS/390) and i5/OS (OS/400)-use NL (New Line, 0x15) as the character combining the functions of line feed and carriage return.ZX80 and ZX81 (Home computers from Sinclair Research Ltd) IBM mainframe systems, including z/OS (OS/390) and i5/OS (OS/400) QNX pre-POSIX implementation (version < 4)Īcorn BBC and RISC OS spooled text output. ![]() Commodore 8-bit machines (C64, C128), Acorn BBC, ZX Spectrum, TRS-80, Apple II family, Oberon, the classic Mac OS, MIT Lisp Machine and OS-9 ![]()
