-- Lingo syntax
foodList = [#Bruno:"sushi"] -- define a property list
trace(foodList) -- displays [#Bruno: "sushi"]
foodList.Bruno = "teriyaki" -- use dot syntax to set the value of Bruno
trace(foodList) -- displays [#Bruno: "teriyaki"]
// JavaScript syntax
var foodList = propList("Bruno", "sushi"); // define a property list
trace(foodList); // displays ["Bruno": "sushi"]
foodList.Bruno = "teriyaki" // use dot syntax to set the value of Bruno
trace(foodList) -- displays [#Bruno: "teriyaki"]
To retrieve a value in a property list, do one of the following:
• Use the list variable followed by the name of the property associated with the value. Place
square brackets around the property.
• Use the getaProp() or getPropAt() methods.
• Use dot syntax.
The following statements use bracketed access to retrieve the values associated with the properties
breakfast and lunch.
-- Lingo syntax
-- define a property list
foodList = [#breakfast:"Waffles", #lunch:"Tofu Burger"]
trace(foodList[#breakfast]) -- displays "Waffles"
trace(foodList[#lunch]) -- displays "Tofu Burger"
// JavaScript syntax
// define a property list
var foodList = propList("breakfast", "Waffles", "lunch", "Tofu Burger");
trace(foodList["breakfast"]); // displays Waffles
trace(foodList["lunch"]); // displays Tofu Burger
The following statements use getaProp() to retrieve the value associated with the property
breakfast, and getPropAt() to retrieve the property at the second index position in the list.
-- Lingo syntax
-- define a property list
foodList = [#breakfast:"Waffles", #lunch:"Tofu Burger"]
trace(foodList.getaProp(#breakfast)) -- displays "Waffles"
trace(foodList.getPropAt(2)) -- displays #lunch
// JavaScript syntax
// define a property list
var foodList = propList("breakfast", "Waffles", "lunch", "Tofu Burger");
trace(foodList.getaProp("breakfast")) // displays Waffles
trace(foodList.getPropAt(2)) // displays lunch
The following statements use dot syntax to access the values associated with properties in a
property list.
-- Lingo syntax

foodList = [#breakfast:"Waffles", #lunch:"Tofu Burger"]
trace(foodList.breakfast) -- displays "Waffles"
