How to pass local variable value to another screen in web application?

I have a input parameter in my home page, I need to have this info also in a second page. 

How is possible?

On the target page, right click the screen in the interface tab and add an Input parameter. Where you have linked to this page it will now prompt for that Input parameter to be filled in on your source page.

You can put in a session variable or pass the value to the new page through the input parameter.
