Aplets

Introduction
Much of the functionality of the HP 39gs is partitioned into packages called Aplets. The HP 39gs comes with 13 HP Aplets, and more can be found
online. Each Aplet is designed to address a specific mathematical topic or set of tasks.
The key to working with HP Aplets is to understand that they were designed to have a similar structure. That structure is illustrated by a set of six keys,
located in two rows of three keys each near the top left of the HP 39gs keyboard. The keys in the first row are SYMB, PLOT, and NUM; the keys in the sec-
ond row are HOME, APLET, and VIEWS. As you saw in the previous section on the Function Aplet, SYMB, PLOT, and NUM control the Symbolic, Graphic,
and Numeric views of the Aplet, which are the main views of all of the Aplets. Two other views, Plot Setup and Numeric Setup, are found by pressing the
SHIFT of PLOT and NUM. Finally, a few Aplets use a Symbolic Setup view, found by pressing SHIFT followed by SYMB. All the data in these views are
saved with the Aplet. Pressing HOME always takes you to the calculation history, which is not part of any Aplet, and thus not saved with any Aplet.
Finally, pressing VIEWS will show you any additional special views that a particular Aplet might have.
Aplets are launched from the Aplet Library. Press APLET and use the UP and DOWN cursor keys to select an Aplet from the library. To launch the Aplet,
press the START menu key, or ENTER.
As you work in an Aplet, you enter data such as definitions of functions, window settings, and preferences of one sort or another. The Aplet records all of
this data and automatically saves it for you. If you leave the Aplet and come back later, all that data is still there. In fact, you can save the Aplet with a
new name and use the original version of the Aplet for another purpose. The new version, under the new name, still has all of your data. You can send
and receive these Aplets from unit to unit, wirelessly, or with a USB connection.
