<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.

saving the workspace data if Octave aborts. The value of
<code>octave_core_file_options</code> should follow the same format as the
options for the <code>save</code> function. The default value is Octave's binary
format.

attempt to save when writing data to the crash dump file (the name of
the file is specified by <var>octave_core_file_name</var>). If
