Whoops.

I just went back and read Technote 80 again (very red face :-).  In the 
first few lines, it states that if SFReply.good is false, SFReply.fType 
contains the ref num of the last selected directory from the SFGetFile 
box.  The above gyrations are not at all necessary.  One simply has to 
look at the reply record to find out what the directory is.  I should 
stop programming late at night - this one walked right by me the first 
time (practically kicked me in the face, too).  Sorry to add traffic to 
the net.
