I have a Preferences object that allows you do use an
ASCII preferences file of the format
KEY = value
The object includes a widget to allow interactive
editting of user preferences. For more info, check

I'm quite sure this is not true. There is no restriction
as far as I know that runtime programs can't create save
files (as long as you are doing nothing but saving variables).
In fact, I have a program here in front of me for one of our
clients that does exactly that on a Windows NT machine.
I don't know off hand if this is a limitation on other
architectures.
Runtime licenses can also write files, so I don't see
any reason you can't easily implement a "preferences
editor", which might, for example, tell the runtime
application where to find the appropriate save file.
Cheers,
David
