@giripappaiya, something like this, I guess. If you need more PDF save options, you can find them in the javascript reference pdf (starting from page 144), and you put them in the SaveOptions_pdf() function in the code.

I tried this and it worked great. Any chance there's a way to tweak it so that it could be used to save newer EPS files as legacy AI files? (I should also note that I just discovered the concept of Illustrator scripts today and have no idea how to create or modify them :))

@strathmoredesigns, should work if you change line 101 to say .eps where it now says .ai.
