Hiya,

You cannot set individual scripts for each item ;
you'll have to script the menu as a whole, and handle
the 'menuPick' message.

Suppose you have a menu with items :
  Alpha
  Beta
  Gamma
  Delta

Example script for that menu button :

on menuPick pWhichItem
  switch pWhichItem
  case "Alpha"
    -- the user chose the item labeled "Alpha"
    -- do what needs done here, before 'break'
    break
  case "Beta"
    -- the user chose the item labeled "Beta"
    -- do what needs done here, before 'break'
    break
  case "Gamma"
    -- the user chose the item labeled "Gamma"
    -- do what needs done here, before 'break'
    break
  case "Delta"
    -- the user chose the item labeled "Delta"
    -- do what needs done here, before 'break'
    break
  end switch
end menuPick

----

An alternative way of scripting the individual items
is the following :

- make individual handlers for what each item needs to
do, in the card script

- put the names of these handlers as a
return-delimited list into a custom property named
"uMenuMessages" in the menu button

- set the script of the menu button to 

on menuPick
  put the menuHistory of me into tPickedLine
  put line tPickedLine of the uMenuMessages \
      of me into tMenuMessage
  send tMenuMessage to this card
end menuPick

----

For more information than you may ever want to know
regarding menus, fire up the Revolution Documentation,
go to the section 'Development Guide' and click on the
item 'Menus' in the left-hand list.

Hope this helped,

Jan Schenkel.
