Ok I have to be doing something dumb. I have read inputs and outputs a hundred times and I still can't figure out how to get an output value to resolve as a string when I need it to build a say a script value for another resource. I have tried

var x = resource.prop.Apply(x => x)

Don’t be hard on yourself: outputs are challenging and take time to get used to. Feel free to ask follow-up questions.

Thx will do
