In your context -string()- maps numeric variables to string. It takes a variable across the big divide. But if you're already across, it is not needed and indeed illegal. Your request needs to be rephrased. The idea of the first 8 numbers of a string makes no sense to Stata. You want the first 8 characters, which no doubt are numeric characters in your case, but that needs a different function. Anyway, it should be easy. Try gen id_v3 = substr(v3, 1, 8) Nick n.j.cox@durham.ac.uk Natalia Batista I´m tring to create a string variable (id_v3) from another string variable (v3). But I want just the 8 first numbers. I tried the following: generate str id_v3 = string(v3,"%-08.0f") By it did not worked. I got the error 109: type mismatch How can I solve it? * * 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/
