Phillip, using Nick's code would in this case probably be best, as it creates both quantities in one run and I think it might be a bit faster than using -egen-. However in the special case you reported, .i.e. your 10 variables do only take values 0, 1 or 2, then you can easily get the desired sum multiplying -egen-'s -anycount- result by 2. egen byte count = anycount(var_101-var_110) ,v(2) g byte sum = 2 * count if count Best Daniel -- [...] I actually needed both, counting the number of variables with value "2": egen var1 = anycount(var_101-var_110), values(2) and computing the sum across these variables (sorry for the imprecise question). * * 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/
