Pass variable from Brightscript to external process

Is it possible to call an external process from Brightscript. For example, once a selection is made with the remote and the next step is executed, could a trigger of some sort be created to send information to an external procedure. When I say external procedure I mean possibly write information to a text file that could be used for something else.
Thanks

If you’re talking about data that you want to persist between sessions or be shared by multiple channels, you could save it to the registry. Multiple different channels signed with the same key can access the same registry space. Other than that, you’d probably need to build a server side solution.
