Hi Monks, I have a question about inserting characters into strings. Before anyone says RTFAQ or some such, this is a bit different than the question or 2 I've found in the Q&A... I have an array of strings of text, mostly UPPERCASE, with intermittent lowercase html tags. I want to insert a space after every 10th UPPERCASE letter, and a newline (and/or html-br) after every 100th, regardless of how many other characters are interspersed between them. My first thought was something like: 
@space = #some array of long text strings;
$n = () = @space;
$i = 0;
while ($i < $n) {
  $space[$i] =~ s/([A-Z]{10}?)/$1 .' '/gxe;
  $i++;
}

And that works great, when there are 10 UPPERCASE in a row, but not when there is any lowercase or brackets separating them. Then I tried some cocamamie bit where I was counting and incrementing after every instance of an uppercase, but I wound up trying to write to $1, which I know is read only. Can anyone enlighten me on a way to accomplish this? Thanks, Matt - -- Matt Dunn - mdunn@stwing.org http://www.stwing.org/~mdunn/
