( #3333=superdoc: print w/replies, xml ) Need Help??

And you don't even need the capturing parentheses:

c:\@Work\Perl>perl -wMstrict -le "my $string = 'IIIIMMMMMMMOOOOOOOOOOMMMMMMMMMMMMMMMIIIIIIMMMMOOOO'; ;; while ($string =~ /M+/g) { my ($start, $end) = ($-[0], $+[0]); print qq{start $start, end $end}; } " start 4, end 11 start 21, end 36 start 42, end 46
Note that  @+ holds the positions of the first character after matched sub-strings!

Give a man a fish:  <%-{-{-{-<

In reply to Re^2: how do you use the index function on this example? by AnomalousMonk
in thread how do you use the index function on this example? by Anonymous Monk

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
