[ncl-talk] Seasonal Variation of Hodogragh

[Dennis Shea]

If you have NCL Version 6.1.1 (February 4, 2013) you could replace the


    time_index(..) = ...

          :

    delete(time_index)


==============

with the reassignment operator

   time_index(..) := ...


*New reassignment operator*

There's a new operator, ":=", that allows you to reassign variables without
having to delete them first.
For example:

   x = fspan(-10.5,20.8,0.1)    ; array of floats
;  x = "This is a string"       ; this won't work
   x *:=* "This is a string"      ; single string

 This operator works for attributes as well, but not for coordinate arrays.
