SAS seems to have withdrawn the treedisc macro from their
web site, presumably because something similar has been
moved to enterprise miner.
I tried it on a simple example and fixed a small
bug in the IML code that caused it to fail [V9].  The new version
can be found at
http://euclid.psych.yorku.ca/SCS/ftp/sas/macros/treedisc.sas

I'm not supporting it, just posting this as a public service.
