Thanks to Kit and Dick for their plugs.
The program -distinct- from Gary Longton and myself is on SSC.
The FAQs Kit refers to discuss other solutions we knew about when
writing them.

Thanks to Kit Baum's gentle prodding I did a little more homework
and found -distinct- written by Gary Longton and Nick Cox
a few years ago. It will find the number of distinct values for
every variable in a list, regardless of whether the variable is
string on numeric and leaves behind the count. Thanks to a;;.
My original message
I would like to loop over the list of variables in a data set and
find the number of unique values for each variable, regardless
of whether the variable is numeric or string. There are several
ways to do this for a numeric variable, but I don't see a convenient
way to do it for a mixture of string and numeric variables.
