[ncl-talk] change global attribute in netcdf file

[Mary Haley]

Chao,

I didn't see any response to this; I apologize for the delay.

Whenever you have "non-standard" variable names like this, you can use the
special $"..."$ syntax to work around it:

att_glb         = True
att_glb@$"VAR-LIST"$= name_value;
fileattdef( fout, att_glb  )

Note that this syntax *only* works when you use it for an attribute name, a
dimension name, or a coordinate variable. Some examples:

x!$"dim-0"$ = "lat"   ; as a dimension name

x&$"latitude-0"$ = (/10,20,30,40/)    ; as a coordinate variable name

You can't use it like this:

$"myvar-0"$ = 58.1
