<emphasis>=</emphasis> (simple assignment) - Put the value of the expression <emphasis>iarg</emphasis> (<emphasis>karg, xarg</emphasis>) into the named result. This provides a means of saving an evaluated result for later use.
</para>

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.
</para>
<para>
From version 5.14 values can be assigned to elements of a vector
with the square bracket form.
