Re: writing recursive function ...

Hi Ufuk,

I was going to write and say that recursion doesn't work in NCL, because I thought NCL had a strict rule about a function being defined completely before you could call it.

But, this small test worked for me:

function factorial(n[1]:integer)
begin
  if (n .le. 1) then
    return(1)
  else
    return(n * factorial(n-1))
  end if
end

;---main code
begin
  n = 10
  x = factorial(n)
  print("factorial(" + n + ") = " + x)
end

You may need to check the types of your variables and attributes to make sure you are not mixing types or dimension sizes.
