I won’t be at JSM, but Agresti is a great author, he’s probably a great speaker too.

For a taste of IML, you can download my 2010 SAS Global Forum paper:

If you like what you see, you might consider a new forthcoming book on IML:

Comment on SAS tip: Why you always should use a RUN statement by Peter Flom

Hi Rick
Thanks! I’ve not used PROC IML, but I have run (!) into the run vs. quit problem on PROC REG.

Great tip. The more complete tip might be “Always use RUN or QUIT.”

In PROC IML, the RUN statement is used to execute modules, so do not use a RUN statement at the end of an IML program.

In general, for interactive procs (such as REG) the RUN statement executes previous statements but does not exit the PROC. It is not until you execute QUIT that output is produced, files are closed, and so forth.
