        !            19: *
        !            20: *  CLAG2Z converts a COMPLEX matrix, SA, to a COMPLEX*16 matrix, A.
        !            21: *
        !            22: *  Note that while it is possible to overflow while converting
        !            23: *  from double to single, it is not possible to overflow when
        !            24: *  converting from single to double.
        !            25: *
        !            26: *  This is an auxiliary routine so there is no argument checking.
