/*Devuelve una cadena que a su vez contiene un número especificado de caracteres de una cadena.

Parámetros
str
    Requerido. Expresión de tipo String de la que se devuelven caracteres.

Start
    Requerido. Expresión Integer. La posición inicial de los caracteres que se devuelven. Si Start es mayor que el número de caracteres de str, la función Mid devuelve una cadena de longitud cero (""). Start está basado en uno.
		
Length
    Requerido. Expresión Integer. Número de caracteres que se va a devolver. Si se omite o si existen menos caracteres del número especificado por Length en el texto (incluido el carácter en la posición Start), se devuelven todos los caracteres desde la posición de inicio hasta el final de la cadena.
