(j3.2006) Compilers disagree

[Van Snyder]

My compilers disagree concerning whether this is legal:

subroutine before ( A, N )
  implicit NONE
  real A(N)
  integer N
end subroutine before

I thought the declaration for N had to precede its use in the
declaration for A, but I can't find the relevant requirement.

Is it there, or am I imagining it?
