  Hello,
 
     I want to match a string against a series of different
   keywords... here is what Ive tried :

   switch(Request) {

      case Request.equals("HELLO"):
            // Write Results to Monitor
           logDisplay.append( "Results: HELLO BACK\n");
           break;
   }

     The compiler tells me I need an int, not a string ... so how do
   you do this common task?
