    Carl:

    The problem is that Linedata and LinePrinter are already the names in the MIB
    and IPP. Would would either have to use those names or create new one. We
    can't really change them.

    Maybe it would be best to break these up into more explicit, separate
    types. Replace LineData and LinePrinter with something like this:

    carriage-control-asa
       A subset of carriage-control-ansi. The print control character (first
       character in record or line) defines the action to be taken before
       printing the current print line. Only these four characters are
       supported:

        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.

    carriage-control-ansi; charset=us-ascii
    carriage-control-ansi; charset=ibm1047 (EBCDIC)
       The print control character (first character in record or line) defines
       the action to be taken before printing the current print line.
    |---------+--------------------------|
    | Characte| Action |
    | r | |
    |---------+--------------------------|
    | blank | Advance one line |
    |---------+--------------------------|
    | 0 | Advance two lines |
    |---------+--------------------------|
    | - | Advance three lines |
    |---------+--------------------------|
    | + | Don't advance - used for |
    | | overprinting |
    |---------+--------------------------|
    | 1 | Skip to channel 1 - |
    | | normally top of form |
    |---------+--------------------------|
    | 2-9 | Skip to channel 2 - 9 |
    |---------+--------------------------|
    | A-C | Skip to channel 10 - 12 |
    |---------+--------------------------|

    carriage-control-machine
       Spacing can occur before or after printing the current line. The print
       control character (first character in record or line) moves to a
       predefined position on the page that is associated with a value of 1
       through 12, known as the channel code.

    carriage-control-evfu
       The print control character (first character in record or line) defines
       the action to be taken before printing the current print line.

               1 advances to the first print line on the next page
               0 skip a line, i.e., double-space
               + over-print the preceeding line
               - skip 2 lines, i.e., triple-space
            (space) print on the next line, single-space

    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

      POSIX.2, X/Open Portability Guide, UNIX System V.
