Chapter 4 / Batch Files
To
use
this
file to format
the
Drive B disk,
enter
the
batch
file
name
and
the
drive specification to replace
%1,
as shown here:
pre
p
dis
k
b:
[ENTER
I
The next two sections tell more
about
creating
and
executing
batch
files
that
have
dummy
parameters.
Creating
a
Batch
File
With
Replaceable
Parameters
The
dummy
parameters
are
%0
through
%9.
MS-DOS always
replaces
the
%0
parameter
with
the
filename of
the
batch
file,
unless
you
use
the
SHIFT
command.
It
replaces
the
other
dummy
parameters,
sequentially,
with
the
parameters
you spec-
ify when you execute
the
batch
file. (See
the
SHIFT command
in
Part
2
if
you wish to specify more
than
ten
dummy
parameters.)
These
parameters
may
be
pathnames,
drive
specifications,
numeric values, or
almost
anything
else. For example,
if
you
type:
copy
con
myfile.bat
[ENTERI
copy
%1.mac %2.mac
[ENTERI
type
%2.
mac
[ENTER
I
t Y P e %0
bat
I
ENTER
I
ill]
[
ENTER
I
MS-DOS
creates
the
batch
file myfile.bat
in
the
current
direc-
tory
and
stores
the
next
three
lines
in
that
file.
When you execute
the
file,
the
parameters
%1
and
%2
are
replaced sequentially by
the
pathnames
you supply.
Executing
a
Batch
File
With
Replaceable
Parameters
To
execute a
batch
file
that
has
replaceable
parameters,
enter
the
batch
filespec (without
its
extension), followed by
the
param-
eters
to replace
the
dummy
parameters.
For example, to execute
myfile.bat, type:
myf
i
le
a:
prog1
b:
prog2
[ENTER
I
myfile is
substituted
for %0, A:prog1
for
%1,
and
B:prog2
for
%2.
