Hi all,
Jim pointed out to me that 'getfilevardims' gets the dimension names
for a particular variable in the file. In order to get all the
dimensions
in a file you should use 'getvardims' (where the 'variable' argument is
set to the NCL file variable.
Also I can report that I have found and fixed the bug in
'getfilevarnames'
called with a list element referencing a file variable.
