Section 10,10: Carriage_Control

 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.

 On U*X systems, this interpretation can also occur if the file is
 processed by the fortpr format utility.

 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.
