@Bulleride I'm going to assume you're studying for certification? 

I've noticed quite a few questions that you've posted on here. I highly suggest that you do more research and google these issues rather than expect to get all your answers from here. Also, if you purchase the SAS Certification guide the examples have worked solutions, since I'm assuming you're working off free test bank questions that you found online somehow, which don't have worked solutions.

@Reeza Yes! I am studying for the same. Went through the SAS base cert book and now solving some questions. Now is almost the time for me and hence asking all my doubts 🙂 I'll buy your suggestion to search for these online. Thanks 🙂

Also, take your time to perform these examples in a SAS session. You'll learn much more from doing it, rather than just reading and asking.

Good luck anyway!
