My current commenting style, although it needs work. You'll have to excuse it's JavaScript-iness, that's all I have handy.
// ========================================================
// COUNT OCCURRENCES (
// STR, // String to search through
// SUB // String to search for
// )
// --------------------------------------------------------
// Counts the instances of SUB in STR. Counts overlapping
// occurrences. Count_Occurrences( 'rrrrr', 'rr') = 4.
// --------------------------------------------------------
function Count_Occurrences ( STR, SUB ) {
var last = 0;
var count = 0;
while ((last = STR.indexOf(SUB, last + 1)) > -1) { count++ }
return count;
}
Update: If you ever spend a year in a country where they don't speak your language, keep a spell checker handy. Alternatively, if my code is used it will only be by non-english speakers, who wouldn't know how to spell 'occurrence' anyway. ;)

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).
