Execute regular expression. Execute the pattern match algorithm using the previously compiled pattern.

The starts# array is filled with as many matches as will fit into the array. If the the array size is zero then it is set to at least one for the first match found.
<p>
The ends# array is set to teh ending position of each substring whose start is returned in the starts# array. This will always be set to the same size as that array.
