> To read it, i say Xstart=1, Xcount(1)=64(X1) and Xcount(2)=32(X2)
> then call nf_get_vara_double(nc,var_id,Xstart,Xcount,X). 
> But somehow this does not work. 'Edge+start exceeds dimension bound'. 
> If i change the Xcount items X1->X2 and X2->X1 i get the values in a wrong 
> sequence. What's wrong. I'm very glad if you would help me.
