The Multics operating procedure began growth in 1964 and employed LF alone as its newline. Multics made use of a device driver to translate this character to whatever sequence a printer desired (such as added padding characters), and the single byte was far more easy for programming. What now seems a far more evident option of CR was not made use of, for a plain CR presented the useful function of overprinting a person line with another to create boldface and strikethrough outcomes, and therefore it was handy to not translate it.
