Thanks for David's plug for my papers on PROC MEANS. I have two available for free download, in PDF Format, from my website, www.sierrainformation.com The first, Steps to Success with PROC MEANS is a beginner level tutorial. You can either download just the presentation or a zip file with the presentation, data sets and SAS code that you can then use to work on the examples yourself. The second presentation, Tips & Techniques for PROC MEANS, discusses some of the more advanced techniques available in PROC MEANS that were added in Version 8, including the IDGROUP option.

To access these, and other papers, go to www.SierraInformation.com and then click on "prsentations" in the upper left hand corner of the home page.

Hope this helps...
