Hi Hua,
I am afraid that there are no such available packages in SAS.
If you have the money, please try to get SAS EM.
If not, I believe you can attempt to write a macro that emulates CART.
Alternatively, you can look into Treedisc Macro written a long time ago for CHAID. This macro requires SAS/IML.

Subject: Regression tree in SAS?
Does SAS have a procedure for “classification and regression tree or recursive portioning analysis”. I noticed SAS has a TREE procedure as part of cluster analysis, which is not what I am talking about here.
Thank you very much for your insight!
Hua
