[ferret_users] cancel mode upcase

[David Wang <climater@xxxxxxxxx>]

Hello Ferreters,

I found CANCEL MODE UPCASE failed to work for user-defined variables. For example:

> yes? use basin.nc
> yes? can mode upcase
> yes? let basin2 = basin
> yes? save/file=tmp1.nc basin
>  LISTing to file tmp1.nc
>  *** NOTE: Converting data type of missing_value NC_SHORT to match output type of variable NC_FLOAT
> yes? save/file=tmp2.nc basin2
>  LISTing to file tmp2.nc

the variable `basin' and all coordinate variables are still in lower case in 
tmp1.nc, but they are all capitalized in tmp2.nc

Is there a reason that it has to be like that?

Thanks,
David
