No:

LineData: Line-data - Lines of data as separate
ASCII or EBCDIC records and
containing no control functions (no CR,
LF, HT, FF, etc.) For use with traditional
line printers. May use CR and/or LF to
delimit lines, instead of records.
ISO 10175 Document Printing
Application (DPA)

LinePrinter: A simple-text character stream which
supports the control codes LF, VT, FF,
and plus Centronics or Dataproducts
Vertical Format Unit (VFU) language is
commonly used on many older model
line and matrix printers.

Then there's the one and only true "line data": ours:

Clearly, none of these matches ASA, which is also described in RFC 740,
Appendix C.

I thought this was either "LineData" or "LinePrinter" in the current
document?????

Another type:  ASA carriage control.  On most Unix systems:  "man asa".

     -Carl




  asa -- Interpret ASA/FORTRAN carriage control


  Format

  asa [file ...]

  Description

  Historically, printouts created by programs use the first character of
  each line to control the spacing between that line and the previous one.
  For example, if the first character is a space, the rest of that line
  immediately follows the previous line; if it is a 1, that line should
  begin on a new page, and so on.

  asa reads input in this format and writes it out in a normal text format,
  using newlines, formfeeds, and carriage returns to achieve the same
  effects as the carriage control characters.

  If you specify files on the command line, asa reads input from these
  files; otherwise, it reads the standard input (stdin).  asa writes output
  to the standard output (stdout).

  It does not copy newline characters in the input to the output. Instead,
  it uses the first character of each line to determine how to print the
  rest of the line. asa interprets the first character as follows:

  Space   Outputs the rest of the line without change.

  0       Outputs a newline character before printing line.

  1       Outputs a formfeed (start a new page) sequence before printing
          line.

  +       Outputs a carriage return sequence so that line is output over
the
          previous line. If + starts the first line, it's treated as a
          space.

  Localization

  asa uses the following localization environment variables:

     LANG
     LC_ALL
     LC_CTYPE
     LC_MESSAGES
     NLSPATH

  See Appendix E, "Localization" in topic D.0 for more information.

  Exit Values

  0  Successful completion

  1  Failure due to any of the following:

        Write error on stdout
        Inability to open the input file

  2  Unknown command-line option

  Portability
