C.l3. $INITDIR - Controlling Time Stamps
EOS
has
the
blessing
capability to
protocol
the
moments
of
file
accesses. Following times
can
be stored for each file:
1. The instant of the most recent access,
2. The instant of the moSt recent alteration,
3.
The instant of the creation of the file.
However,
per file,
only two of these moments can be protocolled.
This
means
that you have to decide whether you want time stamps of access or
time stamps of creation, as these are mutually exclusive.
To make time stamps visible,
the "TIME" option of the $DIR command
has
been created. For details, please refer to the description of $DIR.
The program $INITDIR controls time stamp handling,
The program is menu-
driven.
In this case, no futher explanations are necessary here, as the
program is fully self-explanatory. Its call simply reads:
$INITDIR
In
the
directory,
some space must be reserved for
the
time
stamps.
Hence,
you will find the item "WRITE STAMPS
11
in the $INITDIR menu. When
you
select
this item,
space is created within the directory to
store
time stamps.
Time stamps consume about a quarter of the directory space
available,
so when they are activated, you can create 75 percent of the
otherwise available file entries. Usually, a directory overflow will not
occur. However, if it should happen, you can remove the time stamps from
the directory anytime using the command "ERASE STAMPS",
$INITDIR further offers a facility to name the diskettes,
i.e. the data
media
themselves.
These
names or "labels
11
are displayed in the
upper
left
corner
of the screen when you are inspecting
the
directory.
To
create
such a disk label,
just select the menu item
11
enter
directory
label".
The window then jumps to the field beneath, where the directory
label
is displayed.
Here you may enter a new label of your choice,
To
leave the field without entering a new label, simply press the HOME, the
cursor-up,
or
the cursor-down key.
If you enter a new label,
do
not
forget
to terminate,
as usual,
your input with ENTER so that the
new
label is written to disk.
The
label
can be written separately by selecting
the
command
LABEL
11
•
You
should always do so after having selected the time
mode,
so
that the corresponding control information is written
along with the label.
