Joseph is naturally right. In addition, 1. The help for -split- gives an example in which parsing is on ")" but it is desired to keep the ")" and the answer is simply that if you use -split- in this way you must put them back yourself. This is similar to your problem. 2. The main point is that -split- is not designed directly for this kind of problem because when it was introduced there were already several ways to use existing string functions [N.B., not commands] to solve that kind of problem easily. Joseph has mentioned one. Here's another gen numeral = real(substr(state_name, -4, 4)) gen state = substr(state_name, 1, length(state_name) - 4) Once -numeral- exists, gen state = subinstr(state_name, numeral, "", .) is another way to do it. Here's another gen numeral = substr(state_name, strpos(state_name, "2"), .) gen state = substr(state_name, 1, strpos(state_name, "2") - 1) Nick On Wed, Feb 29, 2012 at 3:49 AM, Joseph Coveney <jcoveney@bigplanet.com> wrote: > Forgot to mention: for this year's survey and afterward, try the alternative below.

I am working with Stata 10. I am working with survey data of Indian states, In the survey data the variable state_name are put jointly with year in which the state is surveyed, in this case 2005 to 2009. So the state_name variable looks like... Andhra2006 Arunachal2005 Assam2006 Bihar2007 UttarPradesh2009 and so on. Now I would like to create two separate variables out of it i.e. state_name and year_survey. I have used the following command split state_name, pares(2) gen(statename) But the problem I am facing is the statename2 variable which is actually year variable is coming without 2 i.e. 005, 006 etc. Please suggest me as I have read the -split- help and Statalist postings on -split- but could not work it out. * * 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/
