<p>The Fortran 95 standard specifies in Part 2 (ISO/IEC 1539-2:2000)
varying length character strings.  While GNU Fortran currently does not
support such strings directly, there exist two Fortran implementations
for them, which work with GNU Fortran.  They can be found at
<a href="http://www.fortran.com/iso_varying_string.f95">http://www.fortran.com/iso_varying_string.f95</a> and at
<a href="ftp://ftp.nag.co.uk/sc22wg5/ISO_VARYING_STRING/">ftp://ftp.nag.co.uk/sc22wg5/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. (Namely, allocatable or pointers of the type
<code>character(len=:)</code>.)
