<term>Assignment:</term>
<listitem>
<para>The equal sign <literal>=</literal> is used to denote the assignment of value(s) to
variable(s). The syntax can be :</para>
<itemizedlist>
<listitem>
<para><literal>a=expr</literal> where
<literal>a</literal> is a variable name and <literal>expr</literal> a scilab
expression which evaluates to a single result.</para>
</listitem>
<listitem>
<para><literal>[a,b,...]=expr</literal> where
<literal>a</literal>,<literal>b</literal>,<literal>...</literal> are variable names and <literal>expr</literal> a scilab
expression which results in as many results as given variable
names.</para>
</listitem>
</itemizedlist>
</listitem>
</varlistentry>
<varlistentry>
<term>Comparison:</term>
<listitem>
<para>The equal sign <literal>=</literal> is also used in the comparison
operators:</para>
<itemizedlist>
<listitem>
<para><literal>a==b</literal>, denotes equality comparison between the values
of the expressions <literal> a</literal> and <literal>b</literal>.</para>
</listitem>
<listitem>
<para><literal>a~=b</literal>, denotes inequality comparison between the values
of the expressions <literal>a</literal> and <literal> b</literal>:</para>
</listitem>
<listitem>
<para><literal>a<=b</literal> and <literal>a>=b</literal> denotes ordering
comparison between the values of the expressions <literal> a</literal>
and <literal> b</literal>:</para>
</listitem>
