Catalogs and editors
The HP 39gs 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.
