<> I think you just want: gen x = . foreach a in `range' { replace x = `a' if !mi(`a') & mi(`x') } Unless I am not understanding your description (if not, an example with some sample data would be useful) Also, note that your loop: scalar i=1 foreach a in {range} { ... gen x={output} in i i++ //or i=i+1 } would not work because you are asking Stata to re-generate "x" each time it passes through the loop. ~ Eric __ Eric A.
