Argument Passing and Sequence Association

For actual arguments in a procedure call, Fortran 90 allows an array element (scalar) to be associated with a dummy argument that is an array. It furthermore allows the shape of a dummy argument to differ from the shape of the corresponding actual array argument, in effect reshaping the actual argument via the subroutine call. Storage sequence properties of Fortran are used to identify the values of the dummy argument. This feature, carried over from FORTRAN 77, has been widely used to pass starting addresses of subarrays, rows or columns of a larger array, to procedures. For HPF arrays that are potentially mapped across processors, this feature is not fully supported.
