Hi All,

Can someone take a look at my script and tell me if I am missing
something as to why the last line of data from my input file is being
written twice in the echo. I have included a short sample of the data
and the script.

Thanks,
Patrick

***Please note that data in this particualr file begins after first
line. I don't have control over this, it's the way I receive the data.***
