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.

 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 
                 current position in 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 the following line), but no 
                 carriage return.

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

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