Main menu puzzle

[Mark Smith]

When your user picks an item from a menu, the rev engine knows that  
this has happened. It also knows which item was chosen.

So it then sends a message "menuPick" to your menu button, to let it  
know that a choice has been made, and it puts the name of the chosen  
menuItem into a parameter which it sends along with the menuPick  
message. Your menu button must handle this message, and make use of  
the parameter. So your menu button needs to have a script containing  
an "on menuPick" handler. You then choose a name for the parameter,  
it could be "pWhich" or it could be "Dave". So:

on menuPick Dave
-- at this point, "Dave" is a variable containing the name of the  
menuItem that was chosen

   switch Dave
     -- you fill in your switch structure with whatever menuItems you  
put in your menu, and handle them as you wish
   end switch	
end menuPick

Hope this helps,

Mark
