Why do you need to do that? You should be able to have one window with
IDL running (constantly), and one window with compilation/running of
the Fortran program... Recompile/run the Fortran program, then re-read
the output file..

I'd recommend either callable IDL or (even better) IDL Remote
Procedure Calls (look in the External Development Guide - edg.pdf in
the documentation library for IDL). It's possible then to make (C)
wrappers that will send your Fortran variables directly to IDL,
execute calls to plot data etc..
The reason why RPC is better than Callable for this instance is that
you can have *two* (or more!) clients connect to the same idlrpc
server, so you can do interactive work as well on the variables sent
over by your Fortran program.
However, unless the above two paragraphs tickle your programmer's
curiosity to learn something neat, I'd just stick with your current
setup (but don't quit the IDL session every time!). Getting something
up and going may take quite some time - so it all depends on how long
you expect to be testing this out interactively...
