[ferret_users] List only valid data points

[Ge Peng - NOAA Affiliate <ge.peng@xxxxxxxx>]

I would like to mask out fields and list only the valid data points. For example,

use coads_climatology

let msk=IF sst GE 26.5 THEN 1 ELSE 0

let sst_msk=sst*msk

list/file=sst_msk.dat/format=(e14.4)/clobber sst_msk         

This lists values for all points. I am wondering if there is a way to list just the non-zero (valid) data points.

Thanks for your help,

--- Peng
