I'm not familiar with Stata, but the easiest may be to call Stata from within SAS - paper here. If you can save the DO file as something else (a DTA or a SAV file, according to what I've read) then you can use PROC IMPORT to get the file into the SAS Environment.
Hopefully you figure this out, and if you can post back your solution here, it'll help future STATA / SAS users 🙂
