Hi David,

Right, a dimension only has a name and a length.  The associated coordinate
variable, which has the same name as the dimension, has the coordinate
values, in the simple case when there is a 1D coordinate variable.

You should be able to read the values from the associated variable using
the nf_get_var_TYPE or nf90_get_var interfaces, depending on whether
you're using F77 or F90.
