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