1 = IWRIRE
For IWRIRE=1, the record file, see Sec. II-3.9, is saved on disc after each iteration is completed. For IWRIRE=0, it is saved only once, after all iterations are completed. This option is useful on systems where the speed of writing large amounts of data to disc could hamper the system performance. For IWRIRE=1, the record file is never saved, and the run cannot be later continued.
