<h2>Initialization</h2>
<p>
<span class="emphasis"><em>=</em></span> (simple assignment) - Put the value of the expression <span class="emphasis"><em>iarg</em></span> (<span class="emphasis"><em>karg, xarg</em></span>) into the named result. This provides a means of saving an evaluated result for later use.
</p>
<p>
From version 5.13 onwards the i- and k-rate versions of
assignment can take a number of outputs, and an equal or less
number of inputs. If there are less the last value is repeated
as necessary.
</p>
<p>
From version 5.14 values can be assigned to elements of a vector
with the square bracket form.
