Slightly modified so that it returns EMPTY value when there is no
prior occurence.
function HighestBetween(expression,array,n)
//Returns the highest ARRAY value between the Nth most recent
//occurrence of True EXPRESSION AND the one prior to that.
{
e=expression;a=array;
Hb=IIf(n>0,ValueWhen(e,Ref(HighestSince(e,a,1),-1),n),
HighestSince(e,a));
return IIf(n>LastValue(Cum(e))-1,Null,LastValue(Hb));
}
