RE: st: Stata commands "version" and "saved results"

[Marco Ercolani <m.g.ercolani@bham.ac.uk>]

Thank you to Nick Cox for pointing me in the right direction.
The answer is simple:

. version 9.2: di c(version)
9.2
. version 9.2: di c(stata_version)
11.1

One can then do whatever one wants with these c(.) codes.

Yours,
 Marco.

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.)
