      dot();
      dash();
      letterspace();
      break;

what want this

code: [select]

switch (var) {
    case 'a':
    case 'a':
      //do when var equals a/a
      break;
    case 'b':
    case 'b':
      //do when var equals b/b
      break;
    default:
      // if nothing else matches, default
      // default optional
  }

of course should really study code posted in other thread liudr. 

hope helps,

brad.
