<a name="index-continuation-lines"></a>

<a name="index-_002e_002e_002e-continuation-marker"></a>
<p>In the Octave language, most statements end with a newline character and
you must tell Octave to ignore the newline character in order to
continue a statement from one line to the next.  Lines that end with the
characters <code>...</code> are joined with the following line before they are
divided into tokens by Octave&rsquo;s parser.  For example, the lines
</p>
<div class="example">
<pre class="example">x = long_variable_name ...
    + longer_variable_name ...
    - 42
</pre></div>

<p>form a single statement.
</p>
<p>Any text between the continuation marker and the newline character is
ignored.  For example, the statement
</p>
<div class="example">
<pre class="example">x = long_variable_name ...    # comment one
    + longer_variable_name ...comment two
    - 42                      # last comment
</pre></div>

<p>is equivalent to the one shown above.
</p>
<a name="index-_005c-continuation-marker"></a>
<p>Inside double-quoted string constants, the character <code>\</code> has to be
used as continuation marker.  The <code>\</code> must appear at the end of the
line just before the newline character:
</p>
<div class="example">
<pre class="example">s = &quot;This text starts in the first line \
and is continued in the second line.&quot;
</pre></div>

<p>Input that occurs inside parentheses can be continued to the next line
without having to use a continuation marker.  For example, it is
possible to write statements like
</p>
<div class="example">
<pre class="example">if (fine_dining_destination == on_a_boat
    || fine_dining_destination == on_a_train)
  seuss (i, will, not, eat, them, sam, i, am, i,
         will, not, eat, green, eggs, and, ham);
endif
</pre></div>

<p>without having to add to the clutter with continuation markers.
</p>
