Dear Statalist user , I need help with stat porgramming. I am working with multiple datasets and with the help of statalist users, was able to figure out a way to use multiple datasets, do data management tasks and save them under separate files My current code is as follows *********************************************** local ds1 "D:\_Dummy\multiple\1\auto_1.dta" local ds2 "D:\_Dummy\multiple\2\auto_2.dta" local ds3 "D:\_Dummy\multiple\3\auto_3.dta" local all ds1 ds2 ds3 foreach x in `all'{ use ``x'',clear include "D:\_Dummy\multiple\4\mpg.do" include "D:\_Dummy\multiple\5\sum.do" save ``x''_new.dta,replace } ************************************************ NOW MY NEW TASK/PROBLEM: I want to create a string variable "year" which needs to be 2000 for auto_1.dta, 2001 for auto_2.dta,2002 for auto_3.dta etc Is could open each dataset and create it myself before starting a the loop. But is there a way to create one OR more variables with different values for different datasets?? within a loop Please let me know. Thank you Sincerely , Mike. * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/faqs/resources/statalist-faq/ * http://www.ats.ucla.edu/stat/stata/
