[Gretl-devel] 'catch' and error messages

Hi, I'm wondering why sometimes there exist informative error messages but it doesn't seem easy to catch them. Here's a concrete (and real-world-inspired) use case: ? m = feval("haha") haha: function not found That's exactly the right error message! However, now I try to retrieve that programmatically: ? catch m = feval("haha") ? eval errmsg($error) Datenfehler # ( = data error) This is much less useful. Could the precise message be pushed through to the error? Hm, I guess there aren't that many formally encoded error types... And BTW, here's a different and a little ironic example: ? m = I(2,3,4) I: zuviele Argumente    # (= too many arguments) ? catch m = I(2,3,4) I: zuviele Argumente ? eval errmsg($error) Befehl hat zu wenige Argumente # (= command with too *few* arguments) So there's a nice contradiction... In addition, I see that even the line with 'catch' does print out the error, whereas I expected it to be silent in that case, no? (I also thought that maybe my German translation was simply wrong and switched to English. I still got "Command has insufficient arguments" for the errmsg.) This is with the March 30th snapshot on Win10. thanks sven
