Howie's idea worked. Thanks everyone. On 2/11/09, Howard Lempel <HLempel@brookings.edu> wrote:This is probably not the most concise code. That being said, try: local start = start_year[1] local end = end_year[1] forval `start'/`end' { do stuff } Hope this helps.

I have tried forval x = start_year[1]/end_year[1] { } but it gives me the invalid syntax error. As for using r(min) and r(max) as per Martin's suggestion, I don't think it will work because start_year and end_year are two different variables. Any other ideas? Here is my question again: I want forval to loop over the (min) value of two variables. More specifically, there is a variable called start_year and another called end_year and what I want is something like this: forval x = start_year / end_year { . . } The variables have all the same value but i want to repeat the same codes across different samples that have varying starting and ending years. This is why I don't want to put the years in numbers as this would create a lot more work. Is there a way to do this? Thanks in advance. * * 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/ * * 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/* * 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/
