Downloaded Aplets & Memory - HP 39g Master Manual

As you can see in the screen snapshot on the previous page, my calculator
has a number of extra aplets. Two of them, Statistics2 and Statistics3 are
simply copies of the normal Statistics aplet containing data that I did not want
to lose. The top two aplets Curve Area and Coin Tossing are teaching aplets
that I have downloaded from the internet.
Downloaded aplets & memory
If you use teaching aplets that you download
from the internet via the Connectivity Kit, or
which are supplied to you by your teacher via
the infra-red link on your hp 39g+, then you
need to bear in mind that most of them have
'helper' programs that aid them in performing
their tasks. In the screens shown right you can
see some of the programs which are attached
to these two teaching aplets. The convention
which most hp 39g+ programmers follow is to
name these 'helper' programs in a way that
associates them clearly with the parent aplet.
The memory associated with these programs is not included in that shown for
the aplet in the APLET view but will not usually be a large amount.
As mentioned on the earlier, pressing
the MEMORY MANAGER screen takes you to a
relevent view showing greater detail. For
example, the Matrices entry right shows 0.1 Kb
in use. Pressing
MATRIX CATALOG view which shows exactly
where the memory is being used and allows
you to delete any or all of the matrices, or you
can enter the view in the normal way by
pressing SHIFT 4.
Calculator Tip
The reason for this naming convention for 'helper'
programs is that when you delete the parent aplet in the
APLET view the 'helper' programs are not automatically
deleted with it. You must change to the Program
Catalog view and delete them manually after you have
finished with the teaching aplet and deleted it in the APLET
view. If you don't do this then they will continue to take up
memory on the calculator. Even on the hp 39g+ this is not
infinite and too many left over programs will eventually
cause problems.
