Script.ReturnValue
Set this variable to 1 (true) or 0 (false) in order to return a true or false status to OL Connect Workflow, when using your script as a conditional branch. This variable will have no effect if the script is run as an action.
If the property is not set, the default value is false.
Example
This example will always return true, as the condition is static. It is, after all, simply an example. You get the idea.
