Example:

```auto
fun appSetOnA(whatever)
fun appSetOnB(whatever)

var caller:String ="OnA"

//call
WHATTODO+"appSet"+caller
```

I guess not right?  
The point is, i got about 20 different functions that returns me an number.  
And insetad of go through a if, switch or when story, would be nice if i could do it that way.

Solutions? Link to a description would be nice to

Reflection might be a way, but it’s often discoureged.

Probably there’s a way better solution given more context. Maybe these 20 functions are not that far apart and you can have some `enum` decribing the behavior and slim that down to a function which takes an enum and returns an `Int`.
