I get that; let me clarify why I asked again.
As far as I'm aware, the actual representation of a string needn't be
the same as its 'physical' value. ie, a string could always appear in
uppercase ('ABCD'), while stored as 'aBcd'. If I need to guarantee that
substr always returned from the physical representation and not the
external appearance, how would I do this? Or, would self, always return
internal representation, (if so, how would I get external appearance?).
Or I could be talking complete _beep_ - in which case I apologise.
Jon.
