Stata can read SAS Version 5 transport files directly. It is my understanding
that SAS Institute does not publicly (or privately) reveal the documentation
for any other of its dataset file types, but rather maintains it as a trade
secret, and so, in principle, although you could write something using -file-
by trial and error, it seems more cost-effective to license a file-conversion
program.
If you have SAS licensed on your system, then you can use -usesas- by Dan
Blanchette, or -odbc- if you have the SAS ODBC drivers installed.
If not, and if you don't mind copy-and-paste routines, you can download the SAS
System Viewer from SAS Institute for free and use that as the intermediary.
You'll loose variable labels and so on, and even although SAS Institute wrote
the program, itself, SAS System Viewer cannot read SAS index files or modern
SAS catalogue files that often accompany SAS data files. Value labels are kept
in the catalogue file.
