Question: Is there an easy way to allow app to exchange data?

Sorry, but I could not find in the documentation where two different 
apps can exchange data between them.  The Manage app scans all the apps 
and retrieves information concerning each.  I reviewed the code and 
could duplicate some of it's function but I was hoping there might be an 
easier way to pass data between two running Helma apps.

Thanks for any suggestions,
Kris
