    <font face="Courier New">Dear all,<br>

      <br>

      I would like to know if there is a fundamental difference between

      functions flts and filter.<br>

      <br>

      For instance performance, accuracy, speed, versatility...<br>

      <br>

      I had asked some time ago but had no answer.<br>

      <br>

      Thanks.<br>

      <br>

      Regards,<br>

      <br>
