Right: the function itself will set the result, and if setting the directory
works the result will not be altered. Only on failure of setting the
directory will the result be changed to indicate failure. Its borderline
that this might be considered a bug, but anyhow its easy to work around:
get myFunction()
put the result into tCheckResult
set the directory to it
if the result is not tCheckResult then
--we have an error
end if
