<h3 class="section">3.1 <code>TMPDIR</code>&mdash;Directory for scratch files</h3>

<p>When opening a file with <code>STATUS='SCRATCH'</code>, GNU Fortran tries to
create the file in one of the potential directories by testing each
directory in the order below.
</p>
<ol>
<li> The environment variable <code>TMPDIR</code>, if it exists.

</li><li> On the MinGW target, the directory returned by the <code>GetTempPath</code>
function. Alternatively, on the Cygwin target, the <code>TMP</code> and
<code>TEMP</code> environment variables, if they exist, in that order.

</li><li> The <code>P_tmpdir</code> macro if it is defined, otherwise the directory
<samp>/tmp</samp>.
</li></ol>
