Switch,Case Structure

[David Vaughan]

There is nothing apparently wrong with your code so forget the 
formatting so long as it works. Parentheses around the switched variable 
are entirely a matter of taste :-). Since you are just now trying 
switch, this demonstrates essentially all its behaviour variations:

-- Demonstrate switch statement (formatting by courtesy of Rev)
on mouseUp
   ask "what value?"
   switch it
   case 1
     answer 1
     break
   case 2
     answer 2
   case 3
     answer 3
   default
     answer "default"
   end switch
end mouseUp

Run it four times,successively  entering 4, 3, 2, 1 and note the effects 
of "break", "default" and the sequence.

regards
David
