I don't understand your question. As your code illustrates, you can
access items such as c(version) directly, so you are not dependent on
whether any command produces them as saved results. -creturn li- gives
this and other constants. It sounds as if you need c(stata_version).
This is all documented in the manuals: [P] is the best place to look.

(And naturally, the result need not be integer.)
