I presume it is because there are fewer than 86 commas on the first line of
that particular file.
You might not care about that, and so you could check for definedness
before checking the length, or you might want to turn off that warning
for a little while. Or it might be showing a real problem in your code
or your data.
You might also be interested in looking into using a third argument for
split().
