Phil is quite correct, but the current version of Stata (10.0) contains an -estimates save- command that allows you to retain and recall estimated results in this or later sessions of Stata.

For example, a common
idiom in R is to fit a model like this:

results <- lm(y ~ x)

This command places the results into an object called
"results" (technically of class "lm"), which one can then use later
on.  In Stata, this would look like:

reg y x
est store results

which would store the estimation results under the name "results" for
further use.  Of course in R you can save the object "results" in a
file, whereas in Stata (at least as of version 9) you cannot save the
set of results in a file (though see Michael Blasnik's -estsave- and
Ben Jann's -estwrite- and -estread- wrappers for a workaround).
