[ncl-talk] Attribute assignment type mismatch on wrf_map_overlays

[Mary Haley]

What version of NCL are you running?

ncl -V

It doesn't really make sense that it's failing on the wrf_map_overlays
line, because I don't think there's an attribute assignment happening
there.  But, if I know what version of NCL you have, then I can look at
WRFUserARW.ncl for that version to see what's happening on the particular
line numbers it's complaining about.
