Re: [Gretl-devel] error catching failing for "catch var..."

Hi, I have the following strange behavior which was a bit difficult to track down. Sorry, cannot give a minimal example because the problem then doesn't appear. In my more complex setup it's reproducible, however. The trigger is a "var 0 endolist" command, which is invalid because the lag order isn't positive. (Actually it's "var km1 endolist; xlist @somestring --silent", and km1 sometimes happens to be 0.) My first minor complaint is that here gretl's error message could be a bit more specific than just "invalid argument".

OK, so I'm trying to use "catch", and immediately after the "catch var" line I have: err = $error if err print err <...> endif But: Now gretl, instead of printing the err and so on, throws another error message "unpaired if" (re-translated from German). How can that be? That must be bogus, because gretl doesn't complain in all those cases where $error==0 (which happens most of the time; all this is inside a random simulation loop).
