[ncl-talk] NCL Error

[Alan Brammer]

Including more of the script will/would help.  

Sounds like bprime is an array, but there was no way for anyone to know that from your initial post. 

Therefore where <https://www.ncl.ucar.edu/Document/Functions/Built-in/where.shtml> is probably what you actually want.  
e.g.

bprime = where( bprime .lt. 0, 0, bprime)   ; see documentation for whats going on here.

No one can do anything with this statement.  Include an error message, an example of why it’s not working, some sample data.
