This setting also applies to the appearance of equations and results
displayed using the SHOW command.
Calculator Tip
Under the system used on the HP39+, if you want to work
in degrees then you will need to choose that setting in the
MODES view and possibly set it again if you change to
another aplet. Some people choose to go through and
change the setting on all the aplets at once so that they
don’t have to remember that it might change. However, if
you the aplet the default setting will return.

One of the major complaints about the hp 38g was its memory - mainly the
lack of it, but also the inability to control or manage it. This problem has been
addressed on the hp 39g+ in two ways. Firstly, the hp 39g+ has over ten
times the useable memory of the hp 38g. At 232 Kb (vs. only 23 Kb), there
are very few users who will come close to filling the hp 39g+. Depending on
size, there is enough room for at least fifty aplets, or for over 10,000 data
points.
The MEMORY MANAGER view
In addition to extra memory, the hp 39g+
supplies a better way to control it through the
MEMORY MANAGER view. If you press the
MEMORY key you will see the view shown right.
Scrolling through it will show you exactly how
the available memory is currently being used.
The remaining memory, in Kb, is shown at the
top right of the screen. This view gives an
overview of the memory. For detailed
management the key is provided.
Pressing on any entry will take you a relevent screen in which you can
delete entries no longer needed.
For example, with the highlight on Aplets,
pressing will take you to the APLET view
(right), where you can choose to delete or
reset any aplets no longer required.
