Pronouns
Description
PowerScript has pronouns that allow you to make a general
reference to an object or control. When you use a pronoun, the reference
remains correct even if the name of the object or control changes.
Usage
You can use pronouns in function and event scripts wherever
you would use an object’s name. For example, you can use
a pronoun to:
-
Cause an event
in an object or control -
Manipulate or change an object or control
-
Obtain or change the setting of a property

You can use the ParentWindow property of the Menu object like
a pronoun in Menu scripts. It identifies the window that the menu
is associated with when your program is running. For more information, see
the PowerBuilder Users Guide.
