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!

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.
