    <title>Performance</title>
    <para>
      <emphasis>tableicopy</emphasis> -- Simple, fast table copy opcodes. Takes the table length from the destination table, and reads from the start of the source table. For speed reasons, does not check the source length - just copies regardless - in &quot;wrap&quot; mode. This may read through the source table several times. A source table with length 1 will cause all values in the destination table to be written to its value.
    </para>

    <para>
      <emphasis>tableicopy</emphasis> cannot read or write the guardpoint. To read it use <link linkend="table"><citetitle>table</citetitle></link>, with <emphasis>ndx</emphasis> = the table length. Likewise use table write to write it.
    </para>

    <para>
      To write the guardpoint to the value in location 0, use <link linkend="tablegpw"><citetitle>tablegpw</citetitle></link>.
    </para>

    <para>
      This is primarily to change function tables quickly in a real-time situation.
