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.
