iProperty Function That Displays String Depending On Boolean

[Starker]

We use iLogic functions to populate the Title iProperty in this general fashion: TYPE: PARAMETER 1, PARAMETER 2, FEATURE 1, FEATURE 2, etc. All of these reference custom iProperties. The "FEATURE" strings should appear in the Title only if the corresponding iProperty is Yes (the design has the feature).

What code do I enter into the Title text field to display a string if an iProperty is Yes?
