In reply to goldmember:
I've worked for SAS (same company, different project), so my knowledge is fairly limited. As far as I remember, it is a programming language, somewhat might be similar to Matlab or R. SAS is a lower level language, hence might be simpler to understand in the beginning. Not so easy to use, sometimes. If you are good at maths or had any programming experience, it would not be too difficult.
Here are some examples of the code:

If so, then you should be proficient. If not, then you might just need to edit few lines of code now and then, and possibly someone else would be able to help you.
