That'll happen if, when minimal (> 0) computational resources are
devoted to finding matching strings across successive 32k blocks of
data, nothing useful is found. 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?
thanks
