26DESCRIPTION
27</b><br>
28<P>
29This sets a maximum length for the number of characters matched by a
30variable-length lookbehind assertion. The default is set when PCRE2 is built,
31with the ultimate default being 255, the same as Perl. Lookbehind assertions
32without a bounding length are not supported. The result is always zero.
