note belg4mit Too be fair, this is a problem with the *current* implementation of qr, and not the concept. Your two regexps are actually: <code> #UPDATE: While the previous verbose format was more # impressive, it was hideously long. See the # readmore for the literal strings. $qq = "[a]"x100; $qr = "(?-xism:[a]"x100 . ")"x100; </code> I think even a newbie could see that the latter is outrageously complicated... <readmore> <code> $qq =<<EOqq; [a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a][a] EOqq $qr =<<EOqr; (?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a]xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a](?-xism:[a]))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))) EOqr </code> <p> <tt> -- <br> I'm not belgian but I play one on TV. </tt> 269035 269061
