HP 38g Graphing Calculator - Manual (Page 24)

Automatic With this example you have defined a new aplet-an aplet
Saving containing data for the solution of y = sin(l/x). The data are
automatically saved in the Function aplet. If you want to create
another aplet based on Function, then you can give this one a
new name in the Library ({{SAVE}}).
To keep as much memory available for storage as possible,
delete aplets you no longer need.
Annotating The Note view (■ [NOTE}) attaches a note to the current
with Notes aplet. See “Notes and Sketches" later in this chapter.
Annotating The Sketch view (■ [SKETCH]) attaches a picture to the
with Sketches current aplet. See “Notes and Sketches” later in this chapter.
Calculating in You can do calculations in aplets wherever you can enter
Aplets numbers or expressions. Use the math keys on the keyboard
or use operations from the | math | menu list. Chapter 2
discusses math calculations.
Catalogs and Editors
The HP 38G has several catalogs and editors. They access
features and stored values (numbers or text or other items)
that are not part of aplets. A catalog lists items, which you can
delete or transmit. An editor lets you create or modify items
and numbers.
