<h5 class="subsubsection">14.1.3.1 Saving Data on Unexpected Exits</h5>
<p>If Octave for some reason exits unexpectedly it will by default save the
variables available in the workspace to a file in the current directory.
By default this file is named ‘<samp><span class="samp">octave-core</span></samp>’ and can be loaded
into memory with the <code>load</code> command. While the default behavior
most often is reasonable it can be changed through the following
functions.
