[Gretl-devel] Re: a certain case where the error message could be more informative

Hi,
I just had to debug a script which failed with a generic "data error".
Gretl correctly indicated the failing line "k++", but it took me a while
to find out that k was undefined at that point. If the error message had
been "unknown object 'k'", it would have been much easier.
Uhm. We do catch that special case: it's the "else" branch in
undefined_symbol_error() from lib/src/genlex.c, where we store the
appropriate message string into the parser struct. The trouble is, it
doesn't get printed, for some reason.
