"Excellent job of reinforcing my knowledge and I even found a few new tidbits. I would recommend these to all SAS Users."

"Thanks again for the great job you did teaching us the basics of SAS. I feel much more comfortable with the language and I understand more about the things I was doing wrong trying to learn it by myself. I also read the recent issue of the Missing Semicolon and found it very useful."
