Depends on the printer. 0x0A on many DecWriters did both a CR and an LF function. That's why UNIX defaulted that way, from what I was told. No need to do any character translation or additions if you just did a "cp" to the device. Of course, Windows via MS-DOS via CP/M-80 used CRLF for the same reason. The PC printers of the day required a separate LF and CR to go to the beginning of the next line. And the CR was done first so that the mechanical time to return the head was taken up by rolling the platten to the next line due to the fact that the CR functino took a "significant" amount of time compared to the LF or printing a simple character. Again, as I was told. > -- John McKown Maranatha! <>< ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
