[Kevin Hallock]

Hi Fuchang,

I found a previous discussion about this issue in an old ncl-talk thread: https://www.ncl.ucar.edu/Support/talk_archives/2010/2040.html <https://www.ncl.ucar.edu/Support/talk_archives/2010/2040.html>

Please try downloading the files linked on that page and put them in the same directory as your NCL script, and then try running your script again.

I will consult with the other NCL developers to determine if find_substring.ncl was intended to be included with NCL or not.

Thanks,
Kevin
