FILE SYSTEM
30
Definition and Explanation
The
File System
provides
a means for
storing
, reviewing, and
editing
text, which
can be divided into separate files (files
can
be copied,
renamed,
or
deleted
whether
they
contain
text
or other
material).
These
files are
stored
in
the
Random Access
Memory
(RAM)
within
the HHC itself or in Programmable
Memory
Peripherals.
In the
HHC,
a file
is
a variable-sized area
within
the
memory.
SNAP files
and o ther
nonprogrammable files are
stored
in
the File
System and can be copied or
deleted
but
NOT
edited, except
to
change the name.
The
Clock/Controller
schedule
also
occupies
the
same
storage
space
(although
it
is
not
listed in
the File
System
Menu),
and thereby effects the
total
amount of
memory
storage
available.
The
use
of
certain
peripherals
also
can reduce
the amount
o
f
available memory.
Current
Memory
An HHC system with
peripherals can
contain
several memory areas:
the
Internal
Memory
is
one
of
them;
each
Programmable
Memory
Peripheral
is another
memory area. Only one
of these
memory areas
is
active at a
time in the File
System.
The listing of
files
in
the File System Menu represents
those
fi
les
in
the
currently
selected
area.
To find the Current Memory, press
liD
,
and
you
will
enter
the
110
Menu.
It lists
all
the
available
memory
areas-the
HHC Primary Unit's
Internal
Memory and all
attached Programmable
Memory
peripherals-plus the number of characters
available for
additional
data
in each memory
area.
The
Current Memory
will
be
displayed
as
an
inverse image: the others normally.
You
can
change
the Current
Memory by typing the
number
from the
110
Menu
of the
memory area that
you wish to
become
the Current
Memory.
Note
that
only one
memory
area
can
be
activated
at
a time, although
other
peripherals in
the
110
Menu
can be in
a
variety
of on and
off
conditions.
This procedure not only gives access
to text
files for
reviewing
,
editing
,
copying.
etc.,
but
it
also locates nonprogrammable
files-
such as
fi
les
needed
to
run
capsule
programs-
and makes
them
accessible
in the
Current
Memory.

File
System from
the
Primary

The Display
shows:

Let

HHC
Internal Memory
is
the Current

it
contains
no files. The
Display then
presents
