I think that TopKatz is right, and it is not 'strange', but 'self-serving'
that there
is no PROC CHAID or whatever it would be called.  Tools like CHAID are
available
in SAS Enterprise Miner, which is an expensive add-on module.

The %treedics macro is around on the internet, along with everything else
that anyone ever put forth.  It may have a few bugs.  I don't know.  But I
do know that it was designed to make some minor improvements over the
original Kass (1980) formulation in a few areas.

HTH,
David
