Try this:

  put return & the short name of this card \
     after the text of button "Menu Name"
  -- use whatever you want as "New Item", of course - can be
  -- "the short name of this card", or a variable, or whatever

You can pull the script into a variable, change the variable, and set the
script property back to the variable (as in SuperCard).

However, if the script is at all long, you'll run into the Starter Kit
limit in setting and compiling the script, so this method isn't ideal.

Can you use a more general menuPick handler that will work no matter what
you add to the menu? For example:

  on menuPick theItem
    switch theItem
    case "Do Something"
      -- some code here for the first menu item
      break
    case "Something Else"
      -- code for the second menu item
      break
    default -- code for all dynamically added menu items
      go card theItem -- or whatever you want to do
    end switch
  end menuPick

This would let your menu react to the added menu items, without having to
add a case for each specific item.
