If it is pure ObjectScript how to write IF ELSE statement in %expression for example? Or can i use RETURN stetement? 

There are situations when you need to return a specific value. The Range expression doesn't work, for example, when you need to determine the display value for Null.

So there's only one way

IF 'value {return "Value is False"} else {return "Value is True"}

But this is wont work

I can still define a class method inside the cube and reference it from within, for example, %cube.CustomLogicClass(%source.DBValue), but that seems redundant. It leaves my cube looking cluttered with simple functions containing only if-else logic.

Thanks for the information, but I would like to see more comprehensive documentation. Such feature rich application and no solid docs anywhere. I think i would create an idea on Ideas Portal about it.

I noticed you've stopped publishing app quality reports since january 2025. Why? You can publish the same information in the moderation section. Reviews aren't useful anywhere except for the app's rating on the platform. Quality reports, on the other hand, show how well developers take care of their apps.
