Re: help loop [Loop end must be scalar]

Hi,

This is an NCL question and should be posted to ncl-talk, not ncarg-talk (which is for NCAR Graphics questions).

"cas1" and "cas1" are multi-dimensional variables that you read off the file. Using them as looping values really doesn't make sense.
That's why you are getting an error that the loop start and end must be scalars.

What do you need to accomplish with this loop?
