                     18: *  =======
                     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.
                     27: *
