One can be found at +<a href="http://user.astro.wisc.edu/~townsend/static.php?ref=iso-varying-string">http://user.astro.wisc.edu/~townsend/static.php?ref=iso-varying-string</a>. +</p> +<p>Deferred-length character strings of Fortran 2003 supports part of +the features of <code>ISO_VARYING_STRING</code> and should be considered as +replacement.
