Re: [ferret_users] List command lists data from down to up but I want it from up to down

Hi Sanaz,

First, you can change the missing-data flag by defining a new variable 
as follows:

yes? let/like=inputvar outputvar = MISSING(inputvar , -9999)

This will make the change for all of the data as it is read from the 
netCDF file, so you do not need to use an IF statement to change the 
values.  When you do a formatted listing, any missing-values will be 
shown as ***.  To write -9999  for the missing data in your listing, do 
not include the "set var/bad=-9999 tmp" command

I am not sure I understand what you are asking about the ordering of the 
listing, and I do not understand your use of M and L in the loop 
structure you are showing.  If you are using repeat loops, you will need 
to use L for time, J for latitude, and I for longitude.  One possibility 
might be to use the LIST/PRECISION qualifier instead of using /FORMAT=f10.2)
