I'd use A/CHDK/DATA.
AFAIK it currently only holds the bootup logo, which is static but I think the directory name is suitable for (more or less temporary) script data as well...

It may not exist, so it should be checked and created with os.mkdir if it isn't there...

fudgey: it also holds the saved script options. As long as your names don't collide with those, it should be OK.

Don't forget what the H stands for.

who else is using it to save script options? just curious what method they're using. i'm using this script - http://lua-users.org/wiki/SaveTableToFile

and i'm quite happy with it so far.

You're probably the first. What reyalp said and I forgot is that CHDK itself uses it to store script parameters for each script nowadays (before that was added, CHDK only remembered user changes to params of currently loaded script and stored it in CHDK config file, now there's param sets and the ability to reset to default parameters in script menu and stores them in A/CHDK/DATA/).
