Unnamed scripts are also created if you create a new script with the name attribute of a script that is

already in the script.user.scripts table. In this case, the name of the script in the

script.user.scripts table is set to an empty string before it is replaced by the new script.

For example, if beepTwoSec already exists in the script.user.scripts table and you sent:

beepTwoSec1200 = script.new("beeper.enable = 1 beeper.beep(2, 1200)", "beepTwoSec")

The following actions occur:

• beepTwoSec1200 is added as a global variable.

• The global variable beepTwoSec remains in the runtime environment unchanged (it points to the

now unnamed script).

• The script that was in the runtime environment as beepTwoSec is changed to an unnamed script

(the name attribute is set to an empty string).

• A new script named beepTwoSec is added to the runtime environment.

In this example, you can access the new script by sending either of the following commands:

beepTwoSec1200()

script.user.scripts.beepTwoSec()

To access the unnamed script, you can send the command:

beepTwoSec()
