Question: You state that CRLF is "traditional". I was under the impression that CRLF originated with CP/M-80 from Digital Research. The LF is from UNIX. I think that the original UNIX predates CP/M-80. Yes, I had a CP/M-80 system many years ago. >From what I understand, CP/M-80 used CRLF because the printers that that were driven from the microprocessor based systems of the time did not implement a "new line" character at all. So, to simplify things, text files were delimited with CRLF on disk so that the "pip" (Peripherial Interchange Program ) program could be used to print a text file simply by "copying" it to "lpt:" (IIRC that was the "name" of the printer). I hadn't noticed that there is not a NL in ASCII. Good catch! <snip> > > -- > Shmuel (Seymour J.)
