Se eu não tenho algo que fme forneça uma faixa de valores, poderia facilmente criar uma função em qualquer linguagem. Algo do tipo make-range(2,5) para me devolver 2 3 4 e 5. Mas se for mais conveniente e deixar o progrma mais legível, posso criar um operador. Muitas linguagens possuem .. que poderia ser utilizado com 2..5 para retornar a sequência. Para fazer em Red 2 .. 5 é muito simples. só assistir ao vídeo.
