Latest revision as of 22:43, 16 November 2012

Create new Screen instance (Screen class)

This shared function instantiates a Screen object.

%screen = [%(Screen):]New

%screen	A declared `Screen` object variable.
`[%(Screen):]`	The optional class name in parentheses denotes a `Constructor`. See "Usage notes", below, for more information about invoking a `Screen` `Constructor`.

As described in "Using New or other Constructors", New can be invoked with no object, with an explicit class name, or with an object variable in the class, even if that object is Null:
%screen = new %screen = %(Screen):new %screen = %screen:new
