If you
the menu and press NOTE then
you would see the Note attached to the aplet.
This is common with these aplets. Since they
are non-standard, the author ensures you have
some instructions, although most of the
®
documentation is generally in a Word
or
®
PDF
document that comes with the aplet.
This particular set of notes consists of a
number of pages, but most are not that
extensive.
Some aplets also have sketches attached to
them but this consumes approximately 1Kb of
memory per sketch and so was not common
on the hp 38g, which only had 23Kb and so
didn't have a lot to spare. On the hp 39g+, as
programmers become used to having plenty of
memory to use, aplets have become larger
and more powerful.
Aplets may also have an attached sketch
which is transmitted with it when it is
downloaded. This is empty by default but
programmed aplets may use it. An example is
shown right of a sketch from one of the aplets
available from HP's web site called 'Periodic'.
This can be viewed via the SKETCH key above the MATH key. Sketches can
have multiple pages and are covered on page 184.

Most users are far more concerned with the Notepad Catalog. Notes held
in it are independent of any aplet rather than being attached to only one, and
can be sent to and received from another hp 39g+ or a computer via the
and
keys in the Notepad Catalog.
The Notepad Catalog can be used to hold an textual material. For
example Physics information or your mathematics homework. As an exercise
here, we will develop a stand-alone Note containing some common formulas.
What notes you are allowed to keep and take into tests is a matter for your
school's or university's policy. It is not a good idea to cheat by taking illegal
material into a test or examination. Quite apart from any other reason, it
could result in severe penalties.
