/sys$common/syshlp/helplib.hlb FORTRAN, Format Specifiers, Carriage Control  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  When the first character of a formatted record is transferred to an
  output file or printer, it can be interpreted as a carriage control
  character (and not printed) if the file is opened with
  CARRIAGECONTROL='FORTRAN' in effect.

  The I/O system recognizes the characters listed below as carriage
  control characters and does not print them.

     Character    Meaning
     ---------    -----------------------------------------
       '+'        Overprinting: Outputs the record (at the
                  beginning of the current line) and a
                  carriage return.

       ' '        One line feed: Outputs the record (at the
                  beginning of the following line) and a
                  carriage return.

       '0'        Two line feeds: Outputs the record (after
                  skipping a line) and a carriage return.

       '1'        Next page: Outputs the record (at the
                  beginning of a new page) and a carriage
                  return.

       '$'        Prompting: Outputs the record (at the
                  beginning of a new page), but no carriage
                  return.

     ASCII NULL   Overprinting with no advance: Outputs
                  the record (at the beginning of the current
                  line), but no carriage return. (ASCII NULL
                  is specified as CHAR(0).)

  Any character other than those listed above is interpreted as a
  space and is deleted from the print line.  If you accidentally omit
  a carriage control character, the first character of the record is
  not printed.
