Specifications
The
other
thing
that
DOS needs to
know
to
find
information
is
"Where"
-that
is, which drive contains
the
diskette
that
has a
particular
file
on
it.
The
drive specifier is a
letter
and
a colon, like
A:,
and
it
tells where
the
file
is.
You
always need
to
type
the
colon
after
the
drive specifier
letter.
The filename and
extension
immediately follow
the
drive
specifier, like this:
A:81PRICES.JUL
Don't
put
any
spaces
between
the
three
parts. These
three
parts
together-the
drive specifier, the filename,
and
the
extension
-are
called a file specification.
Sometimes
you
don't
have
to
type
the
drive specifier;
whenever the drive specifier is the same as
the
default
drive,
you
don't
have
to
type
it.
For
example, assume A: is
the
default
drive
(remember
you
can tell
by
looking at
the
prompt-A>
in this case).
Then
you
could
type
~
....
------
Look-no
drive
a:address
OR
address
specifier!
They
are exactly
the
same
to
DOS
when
A: is
the
default
drive.
Here are some more file specifications:
A:81PRICES.AUG
A:KIKI.J
B:BOWl.BAS
B:MINE
YOURS
~
With this
kind
of
file specification, DOS
r"".,
assumes
that
the
file (YOURS) can
be
found
on
the
default
drive.
