------- Comment #1 from burnus at gcc dot gnu dot org 2007-09-13 13:36 ------- "12.7.3 Elemental subroutine actual arguments" "An elemental subroutine is one that has only scalar dummy arguments, but may have array actual arguments. In a reference to an elemental subroutine, either all actual arguments shall be scalar, or all actual arguments associated with INTENT (OUT) and INTENT (INOUT) dummy arguments shall be arrays of the same shape and the remaining actual arguments shall be conformable with them. In the case that the actual arguments associated with INTENT (OUT) and INTENT (INOUT) dummy arguments are arrays, the values of the elements, if any, of the results are the same as would be obtained if the subroutine had been applied separately, in any order, to corresponding elements of each array actual argument."
