string array[]
long lBound, uBound

lBound = LowerBound(array[]) // = 1, empty array value
uBound = UpperBound(array[]) // = 0, empty array value

array[1] = 'Item 1'
array[2] = 'Item 2'
array[3] = 'Item 3'

lBound = LowerBound(array[]) // = 1
uBound = UpperBound(array[]) // = 3

array[3] = '' //removing item 3

lBound = LowerBound(array[]) // = 1, still
uBound = UpperBound(array[]) // = 3, still (but array[3] is nulled?

I think the line 'array[3]' is wrong, but I think I've read that this should remove the array cell.

What would be the right way to remove an array cell? Does it depend on object type? (String vs Number vs Object)

Or

Can one manipulate the UpperBound value to make it work?

i.e. after removing Item 3, I want the UpperBound, or arraylength, to be 2, since this is logically correct.
