This is DOS misfeature: it won't close a file handle until the batch 
file exits.  (This is why you shouldn't redirect output of a TSR from 
AUTOEXEC.BAT: you'll lose that handle permanently.)  If you really have 
to make so many redirections, I'd suggest using a program from the
``Undocumented DOS'' book, which can detect and release such file 
handles.  Drop me a note if you want more details.
