Hi Philip,
Sorry for taking so long to respond, but thank you VERY much for your very
detailed response. You are right about AS Studio needing an FAQ... I would
pay a lot of money for a good book on it, but it seems like the only decent
book on it won't even be released until June. Apple's documentation is
great to get started, but this list wouldn't have half the bewildered
questions it does if Apple's documentation were more complete!

I am heeding all of your advice... I especially appreciate your comments
about script loading actually loading a copy... I am very close to a
solution because you have steered me off the wrong path and onto the right
one.
I do use the user defaults quite a bit, as well as data sources. The main
elements that are not in these categories are:
- two lists of records that I use to supply the data sources via "append"
- globals that keep track of whether nibs are loaded, etc.
Because I need quick access to the master lists for filtering, etc. I can't
afford the overhead of writing to disk. And my current method of moving the
globals into their respective sub-scripts has given me many headaches,
because of the inherent problems you mentioned.
Unless anyone can correct me, I believe I can accomplish what I need to do
by passing the master lists as parameters for handler calls, and moving the
"global to an application" variables (like the "nib loaded" booleans) back
into my main script.
Any other thoughts?
Thanks,
Graham Jones.
