Dear Nick, Indeed both, I guess. What I don't understand, why the logic of this rule is not applying when in a loop mode: - foreach i of loc list1 { - foreach k of loc list2 { - if "`i'" == "`k'" local d = cond("a" == "c", "%", "Value") = if "a" == "a" local d = cond("a" == "c", "%", "Value") - di "`d'" = di "Value" Value - } - if "`i'" == "`k'" local d = cond("a" == "c", "%", "Value") = if "a" == "b" local d = cond("a" == "c", "%", "Value") - di "`d'" = di "Value" Value - } - if "`i'" == "`k'" local d = cond("a" == "c", "%", "Value") = if "a" == "c" local d = cond("a" == "c", "%", "Value") - di "`d'" = di "Value" Value - } - } Here: = if "a" == "a" local d = cond("a" == "c", "%", "Value") - di "`d'" = di "Value" Value "a" == "a" so why d evaluates to "Value"? 2013/2/14, Nick Cox <njcoxstata@gmail.com>: > In turn I don't understand this new question. > > It seems that you don't understand the code you have written or my > explanation of why the results it gives are perfectly expectable; > indeed both. > > Perhaps you should explain what you want the code to do, because it is > evidently not doing it. > > Nick > > On Thu, Feb 14, 2013 at 4:12 PM, Amadou DIALLO <stata.diallo@gmail.com> > wrote: >> Thanks Nick, >> I have not quite understand your answer.
