with earlier versions of pcretest, <b>-s</b> is a synonym for <b>-m</b>.

<b>-o</b> <i>osize</i>
Set the number of elements in the output vector that is used when calling
<b>pcre_exec()</b> or <b>pcre_dfa_exec()</b> to be <i>osize</i>. The default value
is 45, which is enough for 14 capturing subexpressions for <b>pcre_exec()</b> or
22 different matches for <b>pcre_dfa_exec()</b>. The vector size can be
changed for individual matching calls by including \O in the data line (see
below).
