|
<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>.)
