The default target

A tell expression pushes a new default target. The current default target:

• Is used as the direct object argument for command invocations when none is otherwise specified
• Is asked to handle commands not handled by the direct object (which is consulted first)

This example demonstrates the first point:

tell "hello!"

-- When no direct object is specified, the default command target

-- is used as the direct object:

alert

-- When a direct object is specified, the default target is still

-- consulted to handle the command but is otherwise ignored:

alert "goodbye."

end

This example demonstrates the second point:

tell 9 -- Handled by the integer object '9': sqrt end
