I don't mean to be the bad guy, but this is a horrible solution.
Adding resources to someone else's resource file?  Can you say massive
potential for conflicts?  Can you say forget about network
compatibility if you write into an application file?  Can you say every
sense of programming elegance revolts?

There are a number of other solutions that work much better.  Ben
Cranston pointed out that the dialog item list could have a pointer to
globals appended to the end of it.  I pointed out that you could use
the refCon of your main DA window behind the SF dialog; I also pointed
out that you could write into your DA's code space.  Rich Siegel
suggested using the private storage field of your DA's device control
entry, which you can find by looping through the unit table as
described in a Tech Note.  I'm sure you got other reasonable answers as
well, answers that don't require writing into other people's files
without even knowing what files they are!

That's for sure!  Not even for a second!

There are much cleaner ways that that, believe me....
