I wanted to write a little GUI using Tk to search through a log file of the user's choosing to look for a user-entered pattern. Also, I want to have radio buttons that they can use to modify the matching(i.e., case-sensitive, global, etc.). I tried a silly little driver program just to see if I could do it, and it doesn't seem to work: 

sub driver{
       my $pattern = shift;
       my $modifiers = shift;

       while(<LOG>){
              if ($_ =~ /$pattern/$modifiers){
                           print $_;
               }
               close LOG;
        }
}

ok, there may be typos in that, but then again, there may be typos in the driver program that I have. I looked in the camel and didn't find it. I get an error "string found where operator expected". If there's something up with the way I wrote it, I may have just typed it wrong. Is there anything special I have to do to interpolate the modifiers.
