<h3 class="section">13.1 Entering Debug Mode</h3>
<p>There are two basic means of interrupting the execution of an Octave
script. These are breakpoints see <a href="Breakpoints.html#Breakpoints">Breakpoints</a>, discussed in the next
section and interruption based on some condition.
<p>Octave supports three means to stop execution based on the values set in
the functions <code>debug_on_interrupt</code>, <code>debug_on_warning</code> and
<code>debug_on_error</code>.
