Sorry, but this looks like the same comment to me, and my own view is still the same. Most importantly, -profiler- is not at all the best way to find out how something is done. It's not a service to urge its use when there are better ways to tackle the question, notably -viewsource-. At most, it indicates what programs are called and thus may indirectly suggest where something may be done. Users can naturally have different views on what kind of messages are helpful. The idea of warnings isn't alien to Stata. In general, however, StataCorp style is to issue very few, as you say. In particular, -profiler- does not have this kind of message, and whether that's by accident (as I guess) or design it seems quite right to me. Nick n.j.cox@durham.ac.uk Martin Weiss " The effect of your recommendation would be to add this kind of message to every set of -profiler- outputs, as absolutely no Stata program (strict sense) can act independently of the executable." Stata has come up with so many sensible decisions when to issue messages and when not to (mostly by being conservative), I trust it would manage the problem you are describing quite well. The case Tiago was interested in seems one where my proposed message, cleansed of the histrionics, would make a lot of sense to most users... Nick Cox I don't agree. -profiler- does what it says. The effect of your recommendation would be to add this kind of message to every set of -profiler- outputs, as absolutely no Stata program (strict sense) can act independently of the executable. That might be a useful reminder for a first-time user, but it should rapidly become tedious and pointless on repetition. At most, what it does not do w.r.t. the executable might be made a little clearer in the documentation (if it's unclear; I've not read the manual entry). Nick n.j.cox@durham.ac.uk Martin Weiss True, I overlooked this issue. -profiler- could profit from a note at the bottom of its output to the effect of "Dear user, Stata also dipped its toes into the executable, so you may want to be careful to read too much into my results"... Nick Cox This is correct, but does not much illuminate Tiago's question. -tabi- is just a wrapper for -tabulate- and all the work that concerns Tiago is done off-stage by -tabulate-, which is part of the executable. Thus there is no code that users can look at. Precisely what -tabulate- does is thus a matter for the manual entry. . viewsource tabi.ado is a more direct way to see this.
