The four columns mean:
The
~
column indicates the number of records (a CP
1M
storage unit of
128 bytes)
that
make
up
the file.
The
aytes
column indicates
how
much disk space is used by
the
tile
you
are checking.
The
E.x1.
column
indicates
the
number
of
extents
in
which
the
file
is
stored (one
extent
= 128 records).
The
last
column
in
the
STAT
display,
marked
~,
stands
for
the
access
attributes
of
the
file, as described earlier. A typical
status
line for
the
file
SAMPLE.DOC,
including your command, would look like this:

This would mean
that
the
file
SAMPLE.DOC,
which exists on Drive A, consists
of
27
records of 128 bytes each, is allocated 8 kilobytes
of
the
disk
surface
(even though
27
times
128
is only 3456).
It
uses one extent, and is available
for read and write activity.
In
addition,
the
total
unused space on
the
disk
in
drive A is
422
kilobytes. A kilobyte is 1024 bytes or characters.

If
you would
like
to
protect
a
file
or
diskette
from accidental erasure or
change,
the
STAT
program allows you
to
specify
it
as nread-onlyn. This means
that
(in
the
case
of a program), you can use
the
file, but you
can
make
no
changes
to
the
file as stored on the disk.
To
specify a file as having a particular
attribute,
just enter
