<h3 class="section">10.10 Continuation Lines</h3>
<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> or <code>\</code> are joined with the following line
before they are divided into tokens by Octave's parser. For example,
the lines
<pre class="example"> x = long_variable_name ...
+ longer_variable_name \
- 42
</pre>
<p class="noindent">form a single statement. The backslash character on the second line
above is interpreted as a continuation character, <em>not</em> as a division
operator.
<p>For continuation lines that do not occur inside string constants,
whitespace and comments may appear between the continuation marker and
the newline character. For example, the statement
<pre class="example"> x = long_variable_name ... # comment one
+ longer_variable_name \ # comment two
- 42 # last comment
</pre>
<p class="noindent">is equivalent to the one shown above. Inside string constants, the
continuation marker must appear at the end of the line just before the
newline character.
<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
<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>
<p class="noindent">without having to add to the clutter with continuation markers.
