What is the use of using a!save in save into of interface

Hi sirio,

As you know a! save only works when the user interacts with it, a!save is used for saving the data in a particular variable, 
and you can use multiple a! save in the save into parameter, and also you can use smart service in it.

You are right , 
But you can use only one Smart service within a save into parameter.
and there is a function save!value used to hold the value within the component.
