Paradoxical though it may seem, Allan has got to produce a strongerargument before it can judged exactly how good his proposal is.

The last time we at StataCorp thought carefully about this problem,we learned that it is not enough to write down the statements forwhich the proposal better meets expectations. You have to gosearching for the statements that do the unexpected and then ask,"How easy will that be to explain to users?"

1) http://www.stata.com/statalist/archive/2008-01/index.html#00257 (everything under the subject "My last word on a strange world")

3) an introduction to how NULL values are handled in SQL (e.g., http://en.wikipedia.org/wiki/Null_(SQL))

Others may be able to suggest additional references. -- Phil * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
