Have SAS Eminer? It is part of that. Getting Started with SAS(R) Enterprise Miner(TM) 12.3 (Interactively Train a Decision Tree)
Coming also in VA SAS(R) Visual Analytics 6.2: User's Guide (Working with Decision Trees)
Running in batch is different to interactive. There must be proc for that. It is hidden by these menu-s.
To translate R habits. Language cannot be patented R language SAS language is the same.
Matrix support: SAS - IML this is having a R interface as logical similar
Data preparation wiht R, I see often Phyton being mentioned. SAS has a powefull dataprocessing in its SAS language(s).
All kind of R-packages let us name that by other people developed proceduers... SAS procedures and there are a lot of them.
Searching decision tree in procs...
SAS/OR(R) 9.3 User's Guide: Project Management (Proc Dtree)
SAS/ETS(R) 12.1 User's Guide (Decision Tree and Nested Logit)
All has it specific goal and usage with SAS. It is often bundled as a Solution (tailored for a type of usage)

I don't have eminer.
thanks for the suggestions, but the procs you mentioned don't have the feature i was searching,
I would like for example a CHAID,
PROC DTREE gives a generic decision tree model

Just google on that for the sas site. Chaid analyses is relative old. Most of it, sorry is Miner (google exclude use -miner)
