This sounds like it may be time to put things in a package. Then in
your scripts you could just load the package and use functions. Just
my 2 cents.

If you are running these interactively, you could make your own
source() function. In that function you could define the super and
subscripts, and have it call writeOutput on.exit(). I suspect you
could get something like that to work even in batch mode by having R
load the function by default and some tweaking of your scripts.
