Actually, High(x) is not always implemented as Pred(Length(x)). In routines with open array parameters, Length(x) is actually implemented as Succ(High(x)), because the High value is passed, not the Length value.

 

But you are right about checking for nil and caching the value.

The subject is dynamic arrays and not open arrays.
