The following statements illustrate defining the linear list
workerList
that contains one value,
Heather
, and then adds
Carlos
as the second value in the list.
-- Lingo syntax
workerList = ["Heather"] -- define a linear list
workerList[2] = "Carlos" -- set the second value using the equal operator
workerList.setAt(2, "Carlos") -- set the second value using setAt()
// JavaScript syntax
var workerList = list("Heather"); // define a linear list
workerList[2] = "Carlos"; // set the second value using the equal operator
workerList.setAt(2, "Carlos"); // set the second value using setAt()
To retrieve a value in a linear list:
•
Use the list variable followed by the number that indicates the value’s position in the list. Place
square brackets around the number.
•
Use the
getAt()
method.
The following statements create the linear list
workerList
, and then assign the second value in
the list to the variable
name2
.
-- Lingo syntax
workerList = ["Bruno", "Heather", "Carlos"] -- define a linear list
name2 = workerList[2] -- use bracketed access to retrieve "Heather"
name2 = workerList.getAt(2) -- use getAt() to retrieve "Heather"
// JavaScript syntax
var workerList = list("Bruno", "Heather", "Carlos");
var name2 = workerList[2] // use bracketed access to retrieve "Heather"
var name2 = workerList.getAt(2) // use getAt() to retrieve "Heather"
To set a value in a property list, do one of the following:
•
Use the equals (=) operator.
•
In Lingo only, use the
setaProp()
method.
•
Use dot syntax.
The following Lingo statement uses the equals operator to make
sushi
the new value associated
with the property
Bruno
.
-- Lingo syntax
foodList = [:] -- define an empty property list
foodList[#Bruno] = "sushi" -- associate sushi with Bruno
The following Lingo statement uses
setaprop()
to make
sushi
the new value associated with
the property
Bruno
.
-- Lingo syntax
foodList = [:] -- define an empty property list
foodList.setaProp(#Bruno, "sushi") -- use setaProp()
// JavaScript syntax
foodList = propList() -- define an empty property list
foodList.setaProp("Bruno", "sushi") -- use setaProp()
The following statements use dot syntax to set the value associated with
Bruno
from
sushi
to
teriyaki
.
