Dear Statalist: I have a partial listing of the following variable, formatted as str9: sitecode -------- 37087M022 37087M022 37173M035 37173M035 370810009 370810009 370810009 370810009 370810009 370810009 370810009 370870035 370870035 370870035 370870035 370870035 I would like to create an additional variable, site, as follows: site = xxx if sitecode = 37xxxyyyy. Site is the 3rd, 4th, and 5th characters of sitecode. I don't know how to do this, and what's more frustrating, I don't even know what to input in order to use help. Sorry if this is too basic, but I do appreciate any help. reg * * 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/
