May be I did not explain it well. I added just one line:

== do-file ==
*! tryit.do by Joseph Coveney

version 11.2

set more off

local decision `0'

mata:

if (st_local("decision") == "bail") {
      printf("Bailing out!\n")
      stata("exit = 0")
}
else {
      st_local("decision", "Flying home!")
}
printf("Still there...\n")

end

display in smcl as text "`decision'"
display in smcl as text "do-file terminated normally"

exit
== end of do-file ==

You are "still there" no matter what the `decision' is. And I wanted
to exit before that once and for all.
