Certainly a limitation, not sure if it counts as a bug. As the person
who called for the extension of variable names years ago (from a much
shorter limit) I see what you mean, but I guess it's OK to ask the user
to stay below 28 or 25 characters or so.
Yes, I think we should place a limit of (say) 22 or 24 bytes on
user-specified series names. This would leave room for the prefixes
and suffixes that get added automatically in generating logs, squares,
lags and so on.
If we do that I guess we could still accept names of up to 31 bytes in
third-party data files, but should probably issue a warning.
