Hello,

This is strange but again, I encounter a zero value and sometimes negative for the line. I already post the same issue I encounter before.

Does anyone know how to fix this?

Thanks

Can you say more about the present problem? The meaning of the picture is not obvious to me (but may be to others).

I checked the old thread--but the relation to the current issue is not obvious.

To put it another way: what needs to be fixed?

Do you have sample data? If you have ever seen a negative value for Length (I), that would be very interesting to see!

The only way I can imagine the field for line length displaying a negative value is if the field is converted into an integer and there is an integer overflow - maybe this can happen during some export.

I'd also like to see example data and a brief explanation of what specifically is the issue. If the issue is that the length of non-empty lines becomes zero (or the length of any lines becomes negative) - that's fine, but how were the numbers that we are looking at created, what was the process?
