Good question

For gambas the arrays start always at 0 that is easy,
the ubound is simple the same as s.Count-1

What you had in VB are symbolic index numbers, just as indexes with words
You could delete/remove the first element and the index of the 
remaining stay the same, but are not true in numerical sequence.

The closed to this VB model is using a collection. 
Here the index can be a name or number (as string).

Removing a entry in the collection does not change the index name 
and are called as Key in gambas.

However lbound and ubound are still the same as for normal 
arrays, lboud=0 ubound=collection.count-1
