First off, let me explain what I am trying to accomplish :) I have a string that I want to determine how many times a word appears in. (This must be a case insensitive search) I also need to obtain the count of how many times the word appears in the string, AND I want to modify the string a bit, I want to take the EXACT text that was found as a match, and tag it for HTML bold using and . I have had luck doing this with one minor exception. Note the code below: 
#START CODELET
$Data = "This is the test text for THIS routine.";
$SearchString = "this";
$BoldStart = "<b>";
$BoldEnd = "</b>";
$CountNum -= ($Data =~ s/$searchstring/$BoldStart$searchstring$BoldEnd
+/gi);
print "$Data - $CountNum\n";
exit;
#END CODELET

Note, the output is ALMOST perfect: "this is the test text for this - 2" routine. The output I want is: "This is the test text for THIS - 2" routine. As you can see the text is changed to the searchstring, thus the original caps information is modified. I need to find a way to make the match occur and replace the matched text with itself & the bold tags. Any ideas for an elegant solution, I am not that good yet with the matching functions in perl, thus I need a little help.
