Catalogs and editors

The HP 39G/40G 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.
