Do standard ProDOS subdirectories have a pointer to their parent 
directory?  Or do they have to scan from root to find it?  It seems
that noone implements the equivalent of a .. parameter when they
implement a change directory command (with the exception of APW).
I've never understood why.  It's very useful when you're hopping
from children to parent to sibling directories.
