Re: coordinate to variable

[Mary Quinton <quintonmary@xxxxxxxxx>]

Jimmy,
Ferret lets you use coordinates as variables called
"pseudo-variables".  You can do the kind of thing 
you're talking about with the pseudo-variable Z : 

let zpts = z[gz=temp]
let the=temp[l=1:25,k=1:24]*(1000./zpts)^(287/1005)
