Go back to square one, then: Does an -append- make sense? Does a -merge- make sense? Nick n.j.cox@durham.ac.uk Weichle, Thomas Sorry for the confusion. I was successful in dropping the other variables in epo.dta resulting in 2 variables that remain (study_id, receipt date). Then, I tried to join epo.dta with hgb.dta (which is in memory) containing 3 variables (study_id, test date, test result). After trying the joinby command is where I still received the error saying that there is no room to add more observations. Nick Cox This is unclear to me: 1. What does "try to drop" mean? Did -drop- work? If not, what error messages did you get? Or why say "try"? 2. This description doesn't seem to match your earlier one just a few minutes ago. Here epo.dta has 2 variables. A few minutes ago it included other variables you didn't want and wanted to know how to ignore. I don't think people can easily give good advice if the precise problem is not clear. As in an earlier thread today, the limits of Stata are given by -help limits-. Almost always, the memory available on your machine is what really bites. * * 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/
