[Gretl-devel] strange sum() behavior

Hi, here's something that I find puzzling (snapshot Feb 7): <hansl> clear catch eval sum(1) # error: "no dataset active" catch scalar sc = sum(1) # ditto open djclose.gdt catch eval sum(djclose) # OK catch eval sum(1) # weird printout of all values, almost like 'print 1' catch scalar sc = sum(1) # error: "data types not matched" catch scalar sc = sum(djclose) # OK catch scalar sc = sum(1) # error: "sc is scalar, not acceptable" </hansl> I can understand the first two occurring "no dataset active" errors if gretl interprets the '1' as a series ID which it cannot find. But then: First the behavior yielding the weird printout looks like a bug. Secondly, the final two different error messages is something I don't get. Also bugs? thanks, sven
