The GRAPHICS MANAGER
The LIBRARY MANAGER
There are two views, shown right, for which the only access is via the
MEMORY MANAGER
screen. The first of these, the
GRAPHICS
MANAGER
, shows some memory in use on my calculator due to the
screen captures I am performing to show you these views. Yours will
probably be empty. If you have loaded an aplet from the internet then it
may have used a GROB (Graphics Object) to store an image as part of
its working.
The second view is the
LIBRARY MANAGER
, and this will almost
certainly be empty unless you have games loaded. Generally, the only
aplets which use libraries are those such as games which are written by
expert programmers in machine code in order to make them run as fast
as possible. These games, available on the internet, are listed in the
APLET
view along with the normal aplets and when you delete them the associated library
is
automatically
deleted with them, unlike the case of the ‘helper’ programs.

Because of the amount of memory available on the hp 39gs &
hp 40gs, the Memory View is not one that you will normally need
to worry about unless you store a tru y amazing number of Notes. It
is probably of more interest to programmers.
As discussed later, most games currently available for the hp 39gs
and hp 40gs were originally written for the hp 39g. This can cause
problems in two respects:
The hp 39g was a much slower calcu ator and the games may
simply run too fast to be playable.
Some games were written using programming commands
specifically aimed at the hp 39g chip. When these commands
execute on an hp 39gs or hp 40gs they may cause the
calcu ator to lock up and/or lose user memory. They should not,
however, cause permanent damage.
