Backing Up a File on the Same Diskette
Whether you
have
one drive
or
two
,
you use the COPY FILE
option on the
DOS
Menu to make a backup copy of a file on the
same diskette. Follow the steps oullined under
"
From
One
Disk-
ette to Another With Two
Disk
Drives,"
but type the same drive
code
for
both the FADM and the
TO
filespecs and remember to
give the fife a different name in the TO filespec.
For
example
.
if
you are copying your practice file PROGRAM1
.PIL
on
Drive
1,
you might
type
D1 :PROGRAM1 .PIL ,D1 :PROGRAM1
.

Using Wild Cards to Copy a Group of Files
Suppose you want to make
backup
copies of all four of your prac-
tice files
- PROGRAM1.BAS,
PROGRAM2
.BAS,
PROGRAM3.
BAS
,
and PROGRAM1.PIL You can use wild cards to copy all
four at once
-
a time-saving alternative to copying them one at a
time
.
To use
wild cards to copy all your practice
files,
follow the same
procedure you use
to
copy one file on your system
,
but
use
wild
cards when
typing
your
FROM filespec
(when using COPY
FILE)
or your NAME
OF FILE
TO MOVE (when using DUPLICATE
FI LE). To copy all four of your
practice
files,
for example
,
you
would
type
PROGRAM?
*
as the name of the files to
be
copied
- using the? to stand for the
numbers
in all
four
filenames and
the· to stand
for
the
extenders in all four filenames.
If
you are
using
the
DUPLICATE FILE
option
,
DOS will tell
you
as it copies
each
file.
See Section
3 for detailed
examples of using wild cards when
copying files with COPY
FILE
and
DUPLI
CATE
FILE
