Save a runtime value

Hello guys 

Is there any way to store UFT runtime data permanently?   The methods that I'm looking for is saving value and possible to using it in anywhere and anytime.

a="cccccc" 

Datatable.value("xxxxx")=a

Datatable.export("xx/xx/xx") 

I'm only using above method. But If I need to use in another action,  I have to import excel file again.
