Ok, I've found and fixed that problem. It was related to this FIXME left 
in the code:

{ rewrite (create a new file) }
   { FIX ME: this will just create a new file, actual overwriting
     seems to be a more complex endeavor... }
   if (flags and $1000)<>0 then openMode:=Q_OPEN_NEW;

   res:=io_open(p,openMode);

It was a simple change, Use Q_OPEN_OVER instead of Q_OPEN_NEW as the 
latter barfs with an "already exists" error if the file is there. The 
Q_OPEN_OVER will overwrite any existing file or create a new file, as 
required.

My testing of rewrite is now finished and working. So far anyway!



Cheers,
Norm.
