Tables can be removed from memory using the <a class="link" href="ftfree.html" title="ftfree"><em class="citetitle">ftfree</em></a> opcode.
</p>
<p>
Tables by default, require a size which is a power of two. However tables with any size can be generated by specifying the size as a negative number (see <a class="link" href="f.html" title="f Statement (or Function Table Statement)"><em class="citetitle">f score statement</em></a>).

Not all opcodes accept tables whose size is not a power of two, as this may be a requirement for internal processing.
