Is there a E/G 4.3 book I can get my hands on ?
The SAS for Dummies, Second Edition was written to apply to 4.3. It won't cover some of the new additions, but what it does cover will apply directly to 4.3 as well as 4.2.
The Little SAS Book for Enterprise Guide 4.2 also applies. The 4.3 version of EG has some new features, but everything in the 4.2 version of the book should apply in 4.3 as well.
