Sure enough, the exection error is in this statement in 

WHILE (c.type # dcSentinel) & 
((c.type # dcFree) OR (c.entry.dirInfo.num < direntry.dirInfo.num)) 
DO p := c; c := c.next END;

Seems I need to make a comprehensive study of installable file 
systems and FAT.  For now, this is the Kernel.Log after turning 
on Trace and Detail in the module (and recompiling and 
reloading of course).  OFSFATVolumes should have written a 
raft of information which isn't there.  Enough for now.
