Subject: RE: MI Distinguishing between Blanks and Zeros
In fact, even a blank is not the same as "null". This is a Very Big Deal to

I believe that 47.3 PhD dissertations have been written on this very topic,
with some experts believing that another 9.25 are possible before the topic
is exhausted. (Happy Friday, all...)
