reading in array with dash in name

Hi,

I was wondering if someone could tell me how to read into NCL an array
with a dash in its name (e.g., U-component_of_wind). My line looks like
this:
 U_WND = aa->U-component_of_wind
but NCL thinks this is saying, take the difference of "U" in file "aa"
and "component_of_wind".

If there isn't a way of being able to read in this array in NCL, could
you let me know how to alter the netCDF file to change its name before
reading it into NCL?

Thank you very much in advance.
