To manipulate objects, you use the following set of four commands:

• make new: create a new object of the specified class, and get a reference to it.

  set theDlog to make new dialog

  Here the dialog is created at the first level - it belongs directly to the application. When you create an object as a new element of an existing object (its container), you use the at preposition:

  set theButton to make new dialog item at theDlog with properties thePpties

• delete: delete the specified object. Changes will not be saved.

  delete theButton

• set: change the value of a property of an object.

  set name of theDlog to "my 1st dialog"

• get: evaluates a reference (for instance, a reference to a property of an object).

  set theBounds to (get bounds of theDlog)
  set theItem to (get dialog item 2 of theDlog)

  In many circumstances get is optional, though we recommend to use it systematically, to prevent any unexpected ambiguity.
