Is it possible in Stata 11 to specify varlist as all variables the name of which start with fammem followed by a number between 1 and 10? I will be very grateful for advice, Sincerely yours, Ekaterina * * 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/
