Re: extracting using coordinate subscript

thanks Karin,
let me reframe my question :
I want to retrieve let say two points with coordinates (-20,10) and
(-22,12) I define two variables lat=(/10.,12/) and lon=(/-20.,-22/) and I
want to use these variables as coordinate subscript in a loop to do the
extraction :
can I use this :
ncl 42> pl(i,j)=rr(:,{$lat(i)$},{$lon(j)$})
the points don't have to be contiguous.
Ousmane
sorry for the confusion
