You're right, HyperTalk doesn't have a case statement. You could have coded
your if statement:

on keyDown key
  if key = 'a' then do this else
    if key = 'b' then do that else
      if key = 'c' then do the other
      end if
    end if
  end if
end keyDown

like this instead:

on keyDown key
     if key = 'a' then
          do this
     else if key = 'b' then
          do that
     else if key = 'c' then
          do the other
     end if
end keyDown

Either way you do it, it's uglier than a nice case statement. And harder to
read and understand what's going on.
