End Of Line
     
         (EOL) Synonym for {newline}, derived perhaps from
        the original {CDC6600} {Pascal}.  The abbreviation "EOL" is
        now rare, but widely recognised and occasionally used for
        brevity.  Used in the example entry under {BNF}.
     
        Out of context this would probably be (deliberately) ambiguous
        because different systems used different (combinations of)
        characters to mark the end of a line.  {Unix} uses a {line
        feed}; DOS uses {carriage return}, line feed ({CRLF}) and the
        {Macintosh} uses carriage return.
     
        See also {EOF}.
