  4. Cadena de entrada : false or ( 1 >= 0 ) ; L ::= L:eL opor J:eJ {:Simbolo s = new Simbolo(); s.setTipo(Simbolo.BOOLEANO); s.setValor(eL.getValor() || eJ.getValor()); RESULT = s; :}

  5. Cadena de entrada : false or ( 1 >= 0 ) ; J ::= apertura_parentesis L:eL cierre_parentesis {: Simbolo s = new Simbolo(); s.setTipo(eL.getTipo()); s.setValor(eL.getValor()); RESULT = s; :}

  6. Cadena de entrada : false or ( 1 >= 0 ) ; L:== J:eJ {: Simbolo s = new Simbolo(); s.setTipo(eJ.getTipo()); s.setValor(eJ.getValor()); RESULT = s; :}
