This screen gives a snapshot of the calculator’s memory and of the directory
tree. The screen shows that the calculator has three memory ports (or memory
partitions), port
0:IRAM
,
port 1:ERAM
, and
port 2:FLASH
. Memory ports are
used to store third party application or libraries, as well as for backups. The
size of the three different ports is also indicated. The fourth and subsequent
lines in this screen show the calculator’s directory tree. The top directory
(currently highlighted) is the
Home
directory, and it has predefined into it a
sub-directory called
CASDIR
. The
File Manager
screen has three functions
associated with the soft-menu keys:
@CHDIR
(
A
):
Change to selected directory
@CANCL
(
E
):
Cancel action
@@OK@@
(
F
):
Approve a selection
For example, to change directory to the CASDIR, press the down-arrow key,
˜
,
and press
@CHDIR
(
A
).
This action closes the
File Manager
window
and returns us to normal calculator display. You will notice that the second
line from the top in the display now starts with the
characters
{ HOME
CASDIR }
indicating that the current directory is CASDIR within the HOME
directory.
