        Note that the ECPG implementation differs from the <span class="productname">Informix</span>
        implementation. <span class="productname">Informix</span> limits a long integer to the range from
        -2,147,483,647 to 2,147,483,647, while the limits in the ECPG
        implementation depend on the architecture (<code class="literal">-LONG_MAX ..
        LONG_MAX</code>).
