TRSDO
COPY
/BAS:0 :1
tells
trsdos
to
copy
all
Drive
files
which
have the
extension
/bas. The
files
will be
copied
onto
Drive
1,
using
their
present
file
names
and
extensions.
Sample
Use
Whenever a
file
is
updated,
use
copy
to
make a
backup
file on
another
disk.
You
can
also
use
copy
to
restructure
a file
for
faster access.
Be
sure
the
destination
disk is
already
less
segmented
than
the
source
disk;
otherwise
the
new
file could
be
more
segmented
than
the old
one.
(See
free
for
information
on
file
segmentation.)
To
rename
a
file
on the
same
disk, use
rename,
not
copy.

This
command
lets
you
create
a
file
and
pre-allocate
(set
aside)
space
for its
future
contents.
This
is
different
from the
default
(normal)
trsdos
procedure
in
which
space
is
allocated
to
a
file
dynamically,
i.e.,
as
necessary
when data
is
written
into
the
file.
If you
open
the
file
for
sequential
writes,
trsdos
will
de-allocate
(recover)
any
unused
granules
when
the
file is
closed.
If you
open the
file
for
random
access,
trsdos
will not
de-allocate
space
when the
file
is
closed.
