If you need to calculate the mean, sum, standard deviation, or frequency count for a variable, you'll find it pretty easy to accomplish in SAS Enterprise Guide.

If you've heard anything from SAS in recent months, then you've heard about high-performance analytics and the new SAS Visual Analytics offering. SAS has taken the high-performance analytics message around the world in a series of recent "road shows". From the start, this project has enjoyed a different development process
A SAS Professionals attendee and Twitter follower named Marco asks for help: ..struggling to find a method with custom tasks in EG to be able to list the datasets in a library, can you help please? Sure, no problem. This is easy-peasy-lemon-squeezy. First, make sure that you have a reference
