This is nothing to do with -ds-. It is the problem discussed yesterday in <http://www.hsph.harvard.edu/cgi-bin/lwgate/STATALIST/archives/statalist .1005/date/article-524.html> Namely, the = sign in your assignment truncates the macro as a side-effect. See the above posting for references discussing the problem in nauseating detail. For your problem, there is a very direct alternative. unab a : *_test (Note that unlike -levelsof-, -ds- does not have a -local()- option. But -findname- from SSC, which is a user-written revision of -ds-, does. But for this question, -unab- is far more direct than -findname-, or indeed -ds-.) Nick n.j.cox@durham.ac.uk Dr. Bill Westman I have a question on the function of ds related to the following: forvalues x = 1/50 { g q_`x'_test = 1 } ds *_test ** displays the list of q_1_test - q_50_test perfectly ** local a = r(varlist) disp "`a'" ** DOES NOT Contain all variables. list is truncated after q_25_test q_ ** I'd like to accomplish putting a long list of variables with using "*_" into a local macro (e.g., everything with that has the suffix _test). * * 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/
