See Mark Adler's response at OK, thanks. Of course for my concrete example it's all not very important, it's just about checking whether the user choices are correctly given and honored. But I couldn't find any explanation about "old" vs. "new" missings in the gdtb format, was it about using gretl's own encoding vs. the IEEE missing standard?
