Yes, right.

And as frequently as necessary.  That's why it might be easier just
doing everything a track at a time for very large files.  There should
be an error message when there isn't a whole track to use.  For instance,

   68, no track,xx,yy

See page 356 of INSIDE COMMODORE DOS.  Anybody that is going to be saving
very large files should be able to set a flag so that everything is done
a track at a time.  That would speed things up considerably.
