    Ok,

    I'm trying to count the number of characters in a string. Once the
    count of character's reaches x I want to replace the rest of the
    string with an web site link. So here's what I've come up with so
    far, but I cannot figure out how to do the replace. Can you help me? I
    cannot even get what I have to compile.

    sub replaceLink {
            my ($text) = @_;
            my $textLength;
            my $url;
            my $maxLength;
            my $count;
            my $newText;
            
            $maxLength = 305;
            $textLength = length $_;
            $url = "<a href='somwhere.html'>[View Article]</a>";

            if ($textLength > 305) {
                    $count = 0;
                    while ($text =~ .\g){ # this is the error, . matching
    # any character, g for greed
                            $count++;
                            if ($count == $maxLength){
                                    $newText = $newText . $url;
                            }
                            else {
                                    $newText = $newText . $2;
                            }

                    }
                    return $newText;
            }
            else {
                    return $text;
            }
            
    }
