st:How to do analysis if the same variable exists in one dataset and is missing or contains no observation in another database? |

Dear stata users, I have the same survey conducted in several developing countries. The databases contain almost the same variables (most of the time coded the same way, but differently sometimes). In each database, I want to tell stata to check for a variable, and if it does exist or does contain observations, to perform some task. I coded for example: foreach x of varlist v* { capture confirm existence (`x') if _rc!=0 { sum `x' recode `x' 1=1 2/3=2 4/*=3 } else { display "`x' does not exist or may contain no observation" } But this does not seem to work. I am using stata 8. How to do if the codification for the same variable is different across databases? Many thanks. * * For searches and help try: * http://www.stata.com/support/faqs/res/findit.html * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
