As I said, that was simplified code. I'm writing
a macro to pile objects up (planning later to take
gravity and friction into account.) I want to allow
any number of different objects with different probabilities.
The macro as currently written takes an array of objects and an array of
probailities

eg

// very pseudo-code

#declare ObjectsArray=array[4] {Object1,Object2,Object3,Object4}
#declare ProbArray = array[4] {0.5,0.2,0.2,0.1}

Pile(ObjectsArray,ProbArray)

In the above case 50% of the pile will be object1, 20% object2 etc
