User defined procedure: returning text to user

I am writing a user-defined procedure, and I want to return "text" to the user so the user sees it in the browser after the procedure is completed. A CYPHER example would be:

CREATE (n:PERSON {name: 'John Doe')
RETURN toUpper("task complete")

I understand how to write text to the Log, but that doesn't show up in the browser for the user to see.

Can anyone point me in the right direction?
