Dear Austin, thank you for taking time and writing the actual code. I have already printed the errors list that it produces - excellent reference. But some errors are not captured by the code however, e.g.: assert 1==2 assertion is false r(9); This is probably because not all error codes have messages produced by error(). In the example above, it is probably -assert- itself that writes a message (display as error "assertion is false") and then calls error(9). If I simply call error(9), I don't get the message. So it is a little bit more complicated then that. A quick look at the reference that Kit pointed to, and the output of the program resulted in several of these discrepancies: 6, 7, 9, 170, 399, 409, 416, 420, 480, 482, 491 (stopped comparing at ~500) Some messages have different wording , e.g. 106, 450, which does not change the meaning however. Error code 170 is said to work only for Unix and Mac. Indeed error(170) does not generate a message, but -chdir nonsense- issues this message in Stata for Windows: "unable to change to nonsense r(170);" . It would be rather strange if no message appeared. Interestingly, the program yielded some codes which are not documented 171-176, 403, 464-467 So it seems that both the printed manual and the results of Austin's program are necessary to have a complete reference of Stata's error codes.
