Thanks to Kit Baum the SAS macro savastata that saves SAS data
files as Stata data files has been updated on the SSC archive.
The -usesas- command uses the savastata macro to load a SAS
dataset directly into Stata so if you use -usesas- submit the
Stata command:
. ssc install usesas, replace
This is also the best way of simply updating your copy of the
SAS macro savastata.

There is also a c-shell Unix/Linux script called savas ("save as")
that uses the savastata macro.  This script is similar to the
sas2stata script but it also makes Stata files from SAS files.
It knows what file type to create based on the file extension.
So:
$ savas mydata.dta
creates mydata.sas7bdat
and:
$ savas mydata.sas7bdat
creates mydata.dta

The bug fix in savastata was rather minor, but savastata will
now again preserve SAS formats for special missing values as
Stata value labels.  So:
  .a = "Refused"
  .b = "Don't know"
will be preserved in Stata as value labels.

Best,
