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

Dear NCL users, 


I am try to change global attribute in netcdf file. What I did is: 


att_glb = True 
att_glb at VAR-LIST = name_value; 
fileattdef( fout, att_glb ) 

I happened the error at att_glb at VAR-LIST, It was caused by hyphen sign between VAR and LIST. 
in this attribute. Any suggestions to solve this problem would be very appreciated! 


Thanks in advance, 


Chao
