We wish to write to and read from a simple disk text file in OptoScript (or elsewhere in a strategy) running on an R2. Writing has to occur in real time or very nearly so, as we’re logging asynchronous data. It’s a long-term fixed file, so FTPing a temp file won’t do it.
However, I’m not sure I understand your concern about “FTPing a temp file” – could you tell us a little more about what you’re trying to do?
I’m guessing from what you’ve mentioned so far that writing to the sd card in your R2 would be your best bet ([U][B]now up to 32G w/R9.4a firmware[/B][/U]), but that’s based on some assumptions. Can you tell us more?
