Hi, I am trying to run the %TREEDISC macro of SAS on SAS Enterprise Guide 4.3. I have obtained the two codes from the following links. Treedisc.sas: http://www.public.iastate.edu/~kkoehler/stat557/sas/treedisc.sas/ Xmacro.sas: http://schick.tripod.com/xmacro.sas/ I have changed the following statement to refer to the xmacro.sas-the file containing XMACRO on my system. *%inc '/sas/m611/stat/sampsrc/xmacro.sas'; I am trying to execute the example given in the beginning of treedisc.sas code to run the %treedisc macro. I get the following errors after which the treedisc macro terminates. 17         *** Compute a tree for predicting SPECIES from the petal and 18             sepal lengths and widths, which are treated as ordinal 19             predictors; 20         %treedisc( data=iris, depvar=species, ordinal=petal: sepal:, 21                    outtree=trd, options=noformat, trace=2); ERROR: Procedure IML not found.
