Catalogs and editors
The HP 40gs has several catalogs and editors. You use
them to create and manipulate objects. They access
features and stored values (numbers or text or other items)
that are independent of aplets.
• A catalog lists items, which you can delete or
transmit, for example an aplet.
• An editor lets you create or modify items and
numbers, for example a note or a matrix.
