thanx guys
i think i'll just close the readonly file, open it as writable, use it,
close it, and open the file as readonly.
not elegant at all
but writes will happen on a less frequent basis, less than 1 in 5 i
estimate.
i'd rather save the memory (some computers in use are relatively old
with less than 256mb ram. won't be as responsive and i'd like though.
thanx again.
