| option2; ...optionn: | ||
| where default_option_number is the number of the option | ||
| that will be highlighted by default whenever the choose | ||
| box is displayed, title is the text displayed in the title bar | ||
| of the choose box, and option1...optionn are the options | ||
| listed in the choose box. | ||
