Re: ncl return value

Yes. Not as direct as (say) Matlab but it works ...

Please see the Mini-Language Manual: Sections 2.18 and 5.7
Click "Support" at top of NCL home page ... Manuals

Also:
http://www.ncl.ucar.edu/Document/Manuals/Ref_Manual/NclVariables.shtml

    function foo(...)
    begin
      :
      :
      x = .. ; type float
      y = .. ; type double
      z = .. ; type string

      return( [/ x, y, z /] ) ; return as variable of type list
    end

    ans = foo(...)

    printVarSummary(ans) ; variable of type list

    x = ans[0] ; explicitly extract each return variable
    y = ans[1] ; [..] syntax is for variable of type list
    z = ans[2]
    delete(ans)

Note: There is no need to explicitly extract the list variables.
       They could be accessed as components of 'ans'
