PositionInIndex is the positional equivalent of SubIndex.
Finds U in A and returns the integer position of the value along I. If there are duplicates, the largest such position is returned. PositionInIndex may be necessary when I contains or may contain duplicates, in which case SubIndex isn't sufficient, and without PositionInIndex, there is no easy workaround.
Declaration
PositionInIndex(A:Array[I] ; U : atomic ; I : IndexType )
