Well, if you didn't feel like typing the whole path again you could
always use the Applesoft line edit trick.  If you want to go up a
directory from your example you could do this:

     ]PREFIX
     /HD/PERSONAL/LETTERS/JOE
     ]PREFIX (at this point hit ESC then the up arrow then the left
              hit the left arrow eight times, press space, press the
              left arrow to get the cursor on the letter J of JOE and
              then type BILL and press return)

Your screen ends up looking like this:

     ]PREFIX
     /HD/PERSONAL/LETTERS/BILL
     ]PREFIX 

with the cursor on the P of the last line and your prefix will be
changed.  I've used this trick myself a fair bit.

By the way, the reason that the GSoft BASIC shell supports PREFIX ..
is because I bugged Mike Westerfield to add it.  He wasn't going to
put it in at first because it wasn't available in BASIC.SYSTEM.  :-)
