Thank you Maarten!

The program is actually in this message. If you scroll down you see
inside the message by Michael a bunch of Stata code beginning with:
program define tabvals

and ending with:
end

Copy those lines and store them in a file called tabvals.ado in your
personal adopath. To find your personal adopaht type -adopath- in Stata
and look at the path labeled (PERSONAL). It is probably best to find
the original message by Michael so you won't have to edit out all the
"> >>". Also take care of line breaks.

Hope this helps,
Maarten

 Hello Statalist members,
 This -tabvals- program looks useful. I have searched the Stata site
 and the web without success. Is this a program that can be obtained
 for use?
 Thank you.
