buenas...
alguien lo ha usado?
si es así tiene algún proyecto donde aprender algo?
servirá este componente para las aplicaciones de consola?
Componente Gb.args ( Que Sabemos? )

Humm... según Gambaswiki es una reimplementación de Args que es una clase que funciona como un Array.
En el proyecto gMiaau usaba esa característica que me permitía que al momento de llamar al programa se añadían argumentos estos los tomara como parámetros en el programa. Por ejemplo (lo siguiente hecho con el Scripting de gambas):
si llamas al programa y añades palabras las considerará como parámetros por cada espacio. Ejemplo de llamada
luego del nombre del programa hay 3 argumentos. El args[0] es el mismo programa.
Edito: De la reimplementación, ni idea.

programa.gbs Hola como estás
luego del nombre del programa hay 3 argumentos. El args[0] es el mismo programa.
