Option Menus

[Slava Paperno]

I use a custom property for this purpose. For example, when I use it as a
navigation menu to go to a card that the user selects from an Options
control, my cards have their real names and also each card has a custom
property called DisplayName. Then I use this in the Options control (where
pItemName is the parameter that the control gets when selected)

  repeat with i = 1 to the number of cards in this stack
      if the DisplayName of card i of this stack is pItemName then
         set the menuHistory of me to i
         go to card (short name of card i)
         exit repeat
      end if
   end repeat

Instead of custom properties you can use an array.

I am sure there are smarter ways to do what you want as well, but this
works.

It's the
