[ferret_users] Delete dimension from variable

[A Sdf <asdf1243@xxxxxxxx>]

Hello everyone,
 
I wonder how to delete a dimension from a variable. Let me give an example:
 
I want to create this:
 
                yes? show data
                   currently SET data sets:
                         1> ./SST.nc (default)
                name          title             I          J           K          L
                SOSSTSST SST            1:362   1:292    ...         1:1800

Instead of:
                yes? show data
                   currently SET data sets:
                         1> ./SST.nc (default)
                name          title             I          J           K          L
                SOSSTSST SST            1:362   1:292    1:1       1:1800
in which the K dimension is useless.
 
I have tried to define a new variable using
                yes? Let SST_n = SST[K=1]
                yes? SAVE/FILE=SST_n.nc SST_n
But this did nothing for the problem.
 
Thank you for your help.
