ELSE

        [SIC\]ELSE [IF Logical_expression [THEN]]

    Conditional directive in an IF-END IF block. Similar to Fortran ELSE and
    ELSEIF statements, but note that here the space between ELSE and  IF  is
    compulsory,  while the THEN keyword is optional. If the compulsory space
    bothers you, just define the following symbol
        SYMBOL ELSEIF "SIC\ELSE IF"
